So after about 2 years of searching and saving I was finally able to get the car of my dreams. I have wanted a 49-54 chevy 4 door for about 4 years now. I have been looking off and on the whole time. I didn't want to spend a ton of money as I couldn't afford it but also I would like something that is roughly stock to start with. I went to look at a 54' in San Antonio it was mostly there but had been outside and not running for roughly 20+ years. That deal fell through and in my depression the 49' showed up on craigslist much closer to me and it was much more what I was after. It was the earlier year which I like more, and more importantly it had a newish interior. After speaking with the owner it turned out that he drag races a 54' 2 door in inline 6 club. He had lots of really cool pictures of his dads 52' 2 door from the early 60's when they were racing in Pomona and Bakersfield. He was a really interesting guy, and was super into getting the car to someone who had a interest in taking care of it and not chopping it up.

A little history about the car. It was originally owned by a elderly man and came from California. He had the idea of restoring it, it seems but he was only able to get the interior started and the car painted before he passed away. At that point it was given to his grandson who attempted to drive it for a bit but had no real interest in it. He decided to sell it to Dan the guy I bought it from since he knew that he liked older chevys. Dan purchased the car in 1996 and daily drove the car more or less for about 4 or 5 years until he got married. The woman he married had several small children so he parked it at that point since they were to small to be able to ride in the car. It sat undriven for roughly 16 years that point until he moved to Austin as of a couple of years ago. He decided that point he wasn't going to do anything with it and put it up for sale.

My plans are really just to get it running, finish redoing the interior, and lower it. I think eventually I will think about putting a small block motor in it but that will be later down the line. Most likely I will take the motor out of my truck and replace it with a LS motor and put the trucks motor in the car. Anyways enough words, onto pictures!





You can see my 67' C10 in the background here. It is lowered 5" in the rear and 3" in the front all done with new springs.




Here I hit the hood with some wax to see how the paint would come out. It made a huge difference so Im going to get a buffer and some polish and clean up the paint.




Dan also gave me a exterior sun visor that he got out another 49-54 chevy that he left in the trunk. As best I can tell this one should clip onto the drip rails on the side then grab onto the center post in the windshield. I attempted to lay it out on the car but it doesn't appear to fit. If anyone has any idea what it is that would be super helpful. It appears to be a stock ish one but I am unsure as there are no manufacturer markings on it that I can find.

You want to motorswap a nearly 70 year old car in THAT original condition??? Your car and all that but in all honestly that's one of the best restoration targets I have seen in years. It barely looks like it needs more than cleaning, given it looks amazingly straight and also ridiculously low in rust.

Dunno, I just find original condition old vehicles much more remarkable than modded ones (and that one is quite remarkable). Usually the value reflects that it's the originals that command the best prices in the long run.

It is neat and all that but the straight sixes are not some super special motor. They were used in roughly every chevy / GMC vehicle for like 20 + years. In fact my truck originally had a motor that was not at all that different from the one that is in the car. Putting a SBC in the car would not require much if any modifications to the car anyways. So if I wanted I could always go back to the original motor. Also these kinds of cars are not that super rare in Texas as it is. But I do understand where you are coming from, I would just like to be able to have more power plus I like the V8 sound.

Make sure you've got the correct voltage battery, most if not all cars back then ran 6 volt systems.

You might have gotten lucky on the fuel depending where you live and exactly when it was last driven. The main issue with old gas is the ethanol separating, then absorbing moisture from the air, which rusts your fuel tank out. However, even California didn't ban MTBE, the anti-knock additive that ethanol replaced, until 2003, so you might have the older formulation, in which case just filling the tank and diluting the old stuff would be enough.

Do you have an accessible, inline fuel filter (ie not in the tank)? If so, I'd try and run it for a little bit, then check the filter for rust; if it's clean, you're probably okay.

Sweet car, and that truck is glorious.

Yes the car is 6 volt and I bought a 6 volt battery. I am just going to hit it with starter fluid and pour some gas in the carb to see if it even tries to start. These cars have sort of weird glass filter that is near the carb. But it also has a newer inline filter right by the carb. I am going to take the fuel line off at first to confirm I have good gas in the carb though. I actually have no idea how much gas is in the tank, hopefully the fuel gauge works.

Well after putting a battery and new plugs in, it does crank. I was able to find out that the tank was mostly empty thankfully so I pulled the fuel line off the carb and threw some gas in it. After a little bit of cranking it started pumping fuel. However I am not getting any spark (this was confirmed by pulling one of the plugs and having it sit on the valve cover). I grabbed a new coil since I pulled the cap and it seemed fairly good looking. But still no spark at all, I did notice that when I pulled the cap the points may have been to lose. But even after adjusting them I was getting nothing.

At this point I am really going to need a second hand with it as its hard to tell what is going on just by myself. I am going to grab a new set of points and a condenser because its cheap and why not but I am not confident that will fix it.

Sounds like you need to pull, clean and regap the plugs and maybe change the plug wires and you should be in business. Have you tried a spritz of starter fluid into the carb? If fuel was allowed to sit in the carb it might be getting fuel but clogged up and blocked internally. I love old cars for the simplicity of them.

I currently have no spark. As a general rule plug wires wouldn't cause no spark unless they were ancient which these aren't. Also gapping plugs is not super necessary and would not cause no spark and could tested without a plug. I am getting a new distributor cap as well just to rule it out.

I should also note here that my plugs are brand new.

So even after changing cap, points and condenser I'm still getting no life. I confirmed I got spark at the plugs, and confirmed that the rockers are moving.

So just for shits and giggles I pulled and a plug and shot some starter fluid in it and tried it. Low and behold it tried to fire and that cylinder came to life. Of course directly after that my battery was to weak to turn the motor over. So I am waiting on autozone to charge it.

So I have been driving it around for quite a bit now and some things that I have noticed. The car drives way better then my truck steering is much tighter, and there is actually very few rattles at all. We will see if that continues with it lowered, I'm imagining it will actually be fine then as well.

It is certainly very underpowered, but that is how the truck was originally when I got it as well. It can get out of its own way but it could certainly use another 100 horsepower to be me normal.

I still need to work on the brakes to see if I can get them working better, they are certainly better today then they were yesterday but they can be a lot better. I'm also going to see if I can mount the visor today as well.

So I decided to pull apart the front brakes today to get an idea of what I am dealing with. The brakes seem to be about 90% not working or when they do they stick.



This is what they look like. The wheel cylinder is adjustable on each side which is what those spikey covers are. Underneath the covers is a piston and behind that a spring and two rubber gaskets to hold the fluid. On both sides the Pistons were completely froze. So I pulled them out and cleaned all the crud off. After re-assembling them they appear to at least sort of work now.

However the master cylinder is leaking bad so instead of rebuilding it I am going to get a new one. As getting to it and removing it is its own nightmare. To give you an idea of where it is this is what it looks like from under the car.



It also has some nonsensical woodruff key that is near impossible to get out. I will try and actually take pictures of that since it is going to be full of heartache for sure.

So a little update on the car. I finally decided to tackle the job I have been dreading, replacing the master cylinder (as it was leaking very badly and in general not working well). A normal master cylinder replacement is not a big deal even on my C10. However on the 49' the master cylinder is under the drivers side floor board. Which in itself is not the end of the world. However what makes the whole thing much worse is the fact that the clutch and brake pedals are hinged through the front of the master cylinder.



This is the view from the access panel that is in the back part of the drivers side front wheel well.



This is what you can see from the access panel. The big bolt you see on the front is actually a cover for the woodruff key that holds the brake and clutch arms in place.



The is the view from under the car where you can get a better idea of how the arms connect. There are just two bolts holding the master cylinder to the car. Those are easy to remove.

Once you remove the woodruff key which requires the use of some kind of bent up piece of metal to hook it or just grab it with friction. In my case I used a coat hanger that I bent up and jammed in there. Luckily for me mine was fairly loose and came out easily. Once that was done we then had to try and remove the arms from the master cylinder. I at first just tried to pound out the brake arm. But after much frustration we found that unbolting the brake arm from its pivot (it is a two piece arm) that we can then just slide the master cylinder off of the clutch arm.

The whole thing took about 4 hours of lying on my back covered in grease and what ever else was on the bottom of the car. It was a very finicky job but at least its done and the new master cylinder should be easy to get back in.

My name is LobsterboyX and I approve this thread -

This thing is such a beauty, I love the blackwalls, I love the basic interior, I love the paint, I love this vehicle. So many of my friends have one of these that I feel I've owned one too. It's your car and you can do whatever you wish with it!

about that sun visor, I cant really tell from the picture, but are there screws/bolts on the under side of it towards the middle? if there are, you can open it up and they are adjustable by some tiny set screws in bars at the front and back. I've seen that type before, but have no experience with them. I'm more partial to the Fulton brand which I've been told is the most gangster part of my car:



Before you go the SBC route, take a look here: http://www.cliffordperformance.net/ - also there is a plethora of very cool hop up stuff for the 235, if done well, the little 235 will preform as well as a stock SBC - the easiest things are fenton headders, HEI distributor (that can be disguised to look old), "powerglide" rear end - I cant recall the ratio off the top of my head, but the manual cars were given much lower gears for some odd reason, healthy cam and of course a dual carb setup

another interesting swap is a GMC 6 - they came in a few flavors, but the most popular being the 292 and 302 - Those motors came out of buses and trucks, and can be made beastly very quickly, and the valve covers are bitchin.

lowering the car is dead easy, blocks out back and van springs up front, if you want to go pro, drop uprights. well done brakes stop great, properly grounded 6 volt works just fine, but if you desire the sawp to 12 is dead easy (and you can run a radio and charge your phone) an added bonus is your horns become sonic weapons, I call mine the humiliation horns.

I see you've already discovered the wonders of vintage brake MC's my 48 is like that, my 54 is a little bit further forward, but still very low and my 58 is up high like a modern car, you can tell they were dialing it in.

All in all, great car, and that truck has the most amazing patina ever.

Good work, cant wait to see where you go with this.

Yes the visor is adjustable as you describe. But regardless of how its adjusted it doesn't quite match the curve of the car. I think I could probably make new mounts for the side to make it work. I am not sure if it wouldn't just be easier to trade someone for the correct visor though. I am currently painting the visor black as it was all beat up and multi colored.

I can get some more pictures of the visor if you think you can identify it.

As far as the straight six stuff goes thank you for that link. Any motor changes are not happening for a while. I still need to finish building my motorcycle so it's going to be taking up a lot of my money and time. The car mostly just needs brakes gone through and the window seal leaks bad so it has to get replaced.

I want to keep this thread alive as I am still working on the car. I am currently saving up money to buy a new master cylinder. I am also probably going to convert the front to disc since a conversion kit is about $300 and would be easy to install. The drums up front probably need new wheel cylinders and pads and one of them needs a new drum. That probably adds up to more then the money it would cost to convert.

As a side note I did some catering work out in the country and this happened.

So I haven't been able to work on the car in a while but I got to it recently. I bought a re manufactured master cylinder from O'Reilly's. I was able to get it installed without to much drama. However when we went to go bleed the front brakes we got no fluid out of the bleeders out front. Apparently the rubber lines were clogged or rotted or something. I replaced them and actually had fluid at that point.

I have been working 60 hour weeks with one day off so once I got it to that point I could only work on it once a week really. Originally we bled it but didn't really get it right and there was barely any pressure at the pedal at all. So today I bought a vacuum pump to try and bleed it myself. But that required replacing the bleed screws up front. The original bleed screws did not have nipples on them so you could not hook up self bleeder to them. After attempting to bleed them myself I did not get anywhere. So I had my friend come over and we bled the fronts a bunch of times and as best we could tell there was no air in the lines. We spent the better part of 2 hours trying to bleed the fronts and getting no where. What I had forgotten is that it is a single master cylinder. So if there is air in the system all the brakes will have air. So out of desperation I cracked the bleeders in the back and got nothing but air. So after bleeding the rear brakes finally they work correctly.

What I can say after getting them working correctly is that they are worse then the drums on the truck. I did adjust them so they are probably about as good as they will ever be. So I will probably convert it to disc up front. Its only about 300 dollars and very easy to install. Eventually I will need to convert to a dual master cylinder as well but for no the single will work.

What I need to work on now is the slow starting when hot. I have been told that the 6 volt systems really rely on the connections to the starter and the battery to be very clean. Otherwise there is not enough voltage to get through any crud. Right now it barely turns over when its hot even though the battery has plenty of charge and is brand new. I'm going to try taking the cables off and cleaning them to see if that helps.

Is the starter near the exhaust at all? If it is, maybe wrap the nearby sections in header wrap, or slap a heat shield together?

I know 12V starters don't appreciate heat soak; I would think a 6V would appreciate it even less. Just a shot in the dark though.

The starter motor is on the other side from the exhaust.

I replaced the cable and messed with it a bunch this morning. But it would not even start. Finally I took the battery to autozone to test it. Apparently it would not hold a charge so they replaced it. After that the car started both cold and hot.

So hopefully that resolved that problem and now I await the next problem.

In todays adventures in old broken stuff I bring you the tale of the slow start. So I have been fighting this ever since I got the car running. The car will sometimes be very hard to start when it has been running for a while. As far as I know this is normal with 6 volt cars. However recently it would not start at all and I had to bump start the car. I went and had the battery replaced as it was older and they ordered me a new one. After installing the brand new battery the car was very hard to start cold. I drove it like this for about a day then that night it would barely start and in fact the solenoid got extremely hot.

At this point I pulled the starter and brought it to a starter repair shop who completely rebuilt it. Meaning new windings, pinion gear, armature the whole deal. They also put on a new 6 volt solenoid, they tested that it was working and gave it back to me. Thinking that I had my solution I went home and bolted it on the car got everything hooked up and *Click* the solenoid engages but the starter motor would not. Below is a picture of the wiring for the starter so that you can understand what I am talking about.



So what I have found is that if I jump the hot lead to the switch terminal on the solenoid the solenoid will engage and the starter will turn. The following is what I have done to try and isolate in the car.

-Removed the starter switch and tried to go hot lead to the ground on the switch
-This results in the starter motor sometimes engaging but more often then not just a click.

-Removed the actually lead that comes from the solenoid into the car from the dash.
-Hooked this lead up to the switch with the ground that goes to the solenoid.
-This results in the starter motor sometimes turning but again more often then not I get a click.

-Tried to touch the two leads together in the car (again these are just the other ends of the leads that are connected to the solenoid on the starter).
-I just get a click here.

-Hooked a longer length of heavy gauge wire up to grounded switch lead.
-Tested for resistance on the switch lead to the solenoid.
-No resistance found.

-Repeated this same process but for the hot lead.
-No resistance found on this wire either.

At this point I am seriously at a loss and more importantly I don't know what to test at this point. I should point out that at all times during my I had 6.3 ish volts on the battery and the hot leads at all times. Also if I jumped the hot lead to the switch terminal on the solenoid I can always get the starter motor to run.

Anyone have any ideas here? I really don't want to bring it to someone but at this point I have wasted a week on it and I feel like I farther away from a solution.

Get a wire brush and clean absolutely every connection. If that doesn't work maybe try hooking up an ammeter inline before the solenoid, and after the solenoid and take readings while you turn it over. It should show you if there's a drop somewhere in the system. I think the battery can be ruled out at this point because when you jump it to the switch terminal it turns the motor over. Clearly the starter isn't getting enough juice to turn over.

edit: how are the fuses? I had some bizarre electrical gremlins in my '78 BMW and turns out the fuse connections were corroded and doing weird things they had no right to do.

I think I should clarify here. The diagram posted above shows the wiring coming into the car from the starter and ignition. So there are only three wires that come into the car that involve the starter and ignition. There is a hot lead that brings power to the car, there is the switch wire that goes only to the switch, and there is the power wire going to the ignition.

Something that maybe isn't super clear here is that the starter switch and the ignition switch in this car are two different things. You don't start the car with a key, you lock the ignition with a key. But otherwise if the ignition is on you just press the starter button and it starts the car. So What I did to try and isolate was just take the switch lead and touch to the hot lead in the car. This results in a click and no start. I tested for resistance and grounding on both of those wires and found none.

If you have a good battery and a good starter, somewhere in the circuit is a connection with high resistance. With a 6v system you are more susceptible to resistance issues, which can absolutely be cumulative.

Like was suggested, check where the negative wire meets the frame/block. Also the battery terminals themselves, they have fooled and aggravated me on many vehicles.

What are you meaning when you say you see no resistance? Even a good connection has some resistance, just curious exactly what you're seeing there?

If the ground was a issue it would persist no matter what I was doing. When I say there is no resistance what I mean is that there is no measurable resistance.

Also there is no fuses involved in that part of the circuit.

That makes a little more sense. I'm also going to veer towards "resistance issue" if you can get the starter to fire every time you jump it directly.

At this point we have two points in the circuit. The "good" part which is the battery and starter, and the "bad" part which is the assembly that involves the solenoid, ignition, and the starter button.

I would honestly be really tempted to put an ammeter inline with just the battery and the starter, see what the draw is when it turns over, then do the same with the "bad" part of the circuit also connected. If there is a resistance issue the draw should be larger then. This would at least let you know you're on the right track.

Honestly though, if the wiring is original I would be halfway tempted just to run new wires because strange things happen to old copper.

The wiring in the car is new. I'm going to hook up the switch with wires and see what it does. If that doesn't work then I don't really know.

So I wired the switch up external to the cars wiring harness and it still just clicks and won't turn over. I bypassed the switch and it still just clicks so the switch isn't the issue. At this point the only thing that could be affecting anything is either a ground somewhere or the solenoid itself.

But that being said I don't understand why it will turn over when I jump the solenoid with a big gauge cable.

*Edit*

For clarification when I say a ground somewhere there are only two grounds involved here. The ground on the battery and the ground to the starter. Which the solenoid grounds to the starter which is itself grounded by the connection to the motor.

Okay, so let's take apart your circuit piece by piece.

Have you tried taking a big gauge cable to activate the solenoid in place of the ignition/button? If you can get the solenoid to activate the starter using a different (or no) switch then you can rule out the solenoid.

edit: if it's not clear/obvious physically disconnect the ignition/starter button portion of the circuit before you test the battery/solenoid/starter portion

I took a video showing basically what I have been doing so that you can see whats going on. Also it should be noted that even if I touch the wires without the switch I get the same result.

If you use the switch or touch the wires and only get a click, but using aux cable starts, it's your cable, new or not. Try switch through aux cable.

Thats fine and all but this is how the car was setup and had been working. The only thing that is new to the car here is the solenoid. The big old battery cable is probably just giving me a lot more amperage then I would normally have at that point. Normally the hot lead goes into the car and ties into the harness. The wire that goes to the actual switch is no bigger then the ones that are on it now.

At this point I would have a helper bump the starter button while I observed voltage at each connection point starting at the battery until I found where it dropped. I know you said it was good but I kind of suspect the battery or terminal(s). Either the solenoid isn't getting enough voltage to close, or the solenoid is weak.

What I am guessing is actually the problem is the pinions engagement to the ring gear is much tighter then it used to be. I am getting around this problem by hitting it with way more amperage then it would ever see. When I can get the car to start it sounds very much like the pinion is getting stuck engaged.

Okay so I read back to make sure I knew what was what, issues as you say started after fitting the rebuilt starter and you suspect it's meshed too tightly. Is there any adjustment on fitting the starter to set pinion to ring gear intermesh? If not going back to the shop that rebuilt the starter and explaining the symptoms may yield better suggestions.

Yah that is what I am going to do on Monday.

Does it not have starter shims? Most chevys do And I imagine its not to new of a technology to maybe have been used on the starter. If not just measure the starter and cut some sheet metal shims.

I bought shims and tried to shim it but got the same result.

No shims on that old boy. I just went through/still dealing with 6 volt fun and Im racking my brain right now. Nothing yet but Ive got this thread in my mind.

It really sucks because I have isolated it to the starter at least. But I don't know what the solution is.

So what the starter place told me is that it is the correct pinion. However is most likely very tight because it's new. They are going to try and find my old pinion as it has some play in it which would make it work.

Unsure if this has already been mentioned, but:
- don't put an ammeter inline with a starter unless it's capable of measuring several HUNDRED amps DC, else you will explode it or set it on fire
- measuring resistance on starter wiring (aside from the solenoid triggers, etc) with a regular ohm-meter is useless. Even a hundredth of an ohm of resistance in that circuit will result in several volts drop when the starter is trying to turn, and regular ohm-meters are inaccurate below a few ohms generally (in my experience) even if they read zero when the leads are touched together. Most read 0.2 or 0.4 or so ohms with the inputs shorted, and you're hunting thousandths or hundredths of an ohm, so you're basically trying to measure inches with your trip odometer.

If you want to find the trouble spot without spending a lot of money on a high current DC ammeter or a 4-wire Kelvin-style milliohmmeter, usually it's best to have someone else smash the button while you use your meter set to DC volts to find the wiring connection, piece of wire, or solenoid that has the largest voltage drop across it, then investigate further from there. For instance put one probe on the top of the negative battery stud and the other as far down the battery cable's clamp as you can reach, if you measure more voltage than expected, there's your problem. Or one probe on the top of a starter contactor stud and the other on the ring terminal that is bolted to it, or measure the voltage from that contactor stud to the battery lug it's connected to.

and this is why you want to do it the backyard way instead of buying the equipment to actually measure this kind of low resistance connection accurately, look at those pricetags... :stonklol: https://www.grainger.com/category/milli-micro-ohm-meters/electrical-power-testing/test-instruments/ecatalog/N-b9s

All of that makes sense. Electrical is not the issue here, what ever the problem is mechanical with the pinion. The starter shop let me know they found a old core and pulled a used pinion off of that one.

So I brought the car to the shop down the street yesterday. He basically told he has this exact problem with every rebuilt 6 volt starter he has gotten locally. So he just gets them from some place online now.

So I brought it back to the starter place and told them what was going on. They basically told me to bring the car to them. So I brought it to them and the old guy touched a wire to the positive on the battery and the switch post on the solenoid. It just clicked as it had been doing. At that point he told me the starter was bad. So they have it again and I am supposed to get it back on Monday.


The saga continues!

So the shop replaced the solenoid with a old stock one and now it works without issue. So awesome waste of roughly two weeks of my time.

Oh well it's not like it's a car I drive all of the time. But we didn't get to take it out on thanksgiving when it was beautiful out. Which really bummed me out as that's what I got the car for really. It's great for cruising on nice days, if I had to drive actually I would certainly have a bad time with it.
