Fermented Tinal posted:I don't see how the L05 is gonna hate having to do that, especially since they don't really lose power until like what, 6000rpm? Chevy has historically put some really limp-dicked valve springs in their truck motors, though. I don't know how conservative the factory redline is, but:

cursedshitbox posted:as for bolt pattern? i'm unsure. they look drat close. According to the internet, it should be 10 on 7.25" with a 4.75" center bore.

Elephanthead posted:I think 22 inch rims are easy to find that will fit the rears just fine. For highway spares on your stop at every old truck graveyard journey. From a page back, but: most semi truck wheels are on a much larger (11.25" instead of 7.25") bolt circle, although still 10 bolt. Some 1+ ton trucks use a 7.25" bolt circle, for example the Chevy step van, but the hub diameter changed (wider, thankfully) in 1954 so you'd need hub rings since these wheels are all hub-centric. So, "yes, but." If you can scare up the right adapters, you can run whatever.

Boaz MacPhereson posted:I will throw my vote in for a modern 8.1L BBC though. Nah. Needs a ton of (expensive) parts to make real power, and it shares nothing with the earlier gens (I through VI). GenVII was pretty much a total do-over, to make it more LS-like. But the heads aren't magical like the LS, and there's only one company making heads, cams, intake, etc. If modern-ish BBC is your goal, go with a GenVI and stick a cam in there. That's as modern as you can go to still have plural aftermarket suppliers.

Boaz MacPhereson posted:Are the 8.1s not just the last evolution of the Mark IVs? I know a lot more about SBCs than BBCs so my opinion's not really worth much anyway. Well, sort of. The geometry is pretty similar and the block is based on the Gen6 454, but: Hot Rod posted:Changes were made to the block’s oil-pan rails, all fasteners are Metric, and the 18-point head-bolt pattern (two more than the 396–502) is radically different and doesn’t begin to accept factory or aftermarket big-block heads. Thus, the 8100 block isn’t of much use to traditional Chevy big-block builders Hot Rod posted:The 8100’s LS-style port spacing and 1-8-7-2-6-5-4-3 firing order prevent the use of traditional big-block camshafts. From here: http://www.hotrod.com/articles/gm-vortec-8100-the-454s-forgotten-big-brother/ The only shop making parts for those motors is this guy: http://www.raylarengineering.com/index.html

angryrobots posted:I agree it's not any use for hot rodding, but it's a good truck motor, and an aftermarket tune (getting rid of GM torque management) will get some very usable low end grunt. I guess so, but if Sims wants a big block I think he can do better with a late model 454 and some goodies, a la the engine in Stubby Bob, which made 428HP/507ft-lb with just a cam and springs. E: I suppose, though, if this is going to be a fairly high-spend project, Sims can always just throw the Raylar catalog at an 8100 and make good power. I just like the apparent relative ease of making the GenVI get up and go. Raluek fucked around with this message at 00:30 on Dec 23, 2016 |

This is the closest thing to "information" I can find for 7.50R20 LRG: So looks like you can go up to 120psi, depending on corner weights. From here:http://www.sullivantire.com/uploadedFiles/Bridgestone%20Truck%20Data%20Book.pdf

19 o'clock posted:So...I suppose I misunderstood how things work relating to steering. I saw a steering box and imagine that it meant power steering, but apparently it's not the case? All that the steering box is on this truck is a gear box? I guess I always imagined manual steering to be a simple bit of linkage at the base of the column/shaft that manipulated things. No, vehicles with non-assisted steering still need mechanical advantage. Really, they need it more than assisted steering, since you're doing it all with upper body strength. So there's probably a worm gear and a sector gear in there.

Fermented Tinal posted:So, do the truck gauges work or are you going to have the vangauges ride shotgun? I'd imagine that the answer to that is "yes." He's using the truck's original trans, so the speedo should work (if it worked in the first place). But it's using the van fuel tank, so (if it got hooked up) the fuel level will have to come from the van cluster. And if the van had a tach, it would be that one too. So probably some of both! Unless the van had a cable-operated speedo, in which case I guess he could plug the truck's speedo cable into it and have everything on one cluster.

You can also skip buying a Y-pipe by getting a 2-input 1-output muffler like this one: https://www.summitracing.com/parts/aph-700359/

Bud K ninja sword posted:hey dude ups trucks are cool. There was a picture of a field with a UPS truck in it, that was initially mis-identified as a Divco. That's where it came from. But, I agree, that's kind of neither here nor there for this thread. I think March or April was the tentative re-start date?

ExplodingSims posted:My only real criteria would be something modern-ish, with fuel injection. Well that eliminates all the big block options I was going to suggest. Only the 8100 had decent injection, and it doesn't share any parts with regular BBCs. So yeah, probably looking at a diesel, sadly.

Maybe a Cummins? That's a good point. BBC would probably have all sorts of problems with that steering box. Left Ventricle posted:You really can't go wrong with an LS. This is definitely true. I'm not sure it will have the stump-pulling torque that a truck like this would be best suited by, though? Raluek fucked around with this message at 03:12 on Jan 11, 2017 |
