Found your donor: 97 1500. L31 on the tag, everything looks right. I can get em for $100 for the pair hopefully this Saturday if you say the word.  There were a handful of other donors but they all looked worse than this one - open corroded throttle bodies, collision damage, etc.

I'd say that's a perfectly AI suggestion because it might be cheaper than actually retrofitting the factory roller cam setup to the '92 block. The only possible downside is the L31 block will definitely not have any provision at all for a mechanical fuel pump. You know, for if the fuel injection magically falls off and you just have to slap a tunnel ram and a pair of four barrels on it.

Honestly my suggestion would be slam an LM7 in it whole with a set of aftermarket mounts and splice up a quick harness. But he's got this giant boner for a thumpr cam for some reason and keeps talking about maybe carbing an engine that already came with perfectly alright TBI, so I am staying the gently caress out of the way and not turning wrenches on this thing, I'll do parts acquisition but my input is definitely not needed on How To Do This. Note I say LM7 not LQ4/9 because I saw six I could get whole for 300 each today... E: that and I can't in good faith suggest a whole block change without helping do it, because it looks miserable on a van body. kastein fucked around with this message at 18:14 on Jan 7, 2016 |

He doesn't want a roller cam, and if he did it's literally just the spider and 8 dogbones that you can pocket when you grab the heads. Plus, he's keeping the TBI, plus who wants to change a short block in a van when you can do just heads? If the van's short block is in good shape it's mechanically no different than the L31 anyway (assuming they both have the same number of mains bolts)

The giant boner for the thumpr is because if I'm gonna have a small block chebby it's gonna lope, dammit, and the thumpr has the best sounding lope I've come across. I can be talked out of the thumpr, but yeah, it can be had for LSes too. I could be convinced to throw an LS motor in there (such as the LM7) - as mentioned, the thumpr works with those too, and AIUI the GM LS ECU has been so widely modified it might as well be a standalone. I don't so much not want a roller cam as fail to see the point in spending $$$ extra just to get a roller setup. The idea of throwing a factory roller block in had occurred to me, but the cam itself is still 2x the price of a flat tappet cam, and lifters are another hundred bucks. Both the L31 and the L05 are 4-bolt mains, the short blocks might as well be identical. Neither really has provisions for a mechanical fuel pump, but electric fuel pumps for carbs can't be that expensive. Again with the carb thing it's less a question of what I'd optimally want to do and more a question of bang for buck. From what I've read the stock TBI (which I'd have to buy a $400 manifold to make work with the Vortec heads thanks to the different bolt pattern) won't particularly enjoy any lopey cam, and any/all modifications I can find to make it happy land up costing $230 for a ported throttle body and $300-400 for reprogramming the PCM. By that point (including the manifold) I've spent ~$1000, and I might as well just throw a cheap Holley 4150-pattern manifold on with a $450 carburetor. I'm still really not super happy with running a carb, but it's what Adiabatic's SBC-nut friend recommends, and he's volunteered to tune the thing, so it's probably going to get the holley on sheer bang-for-buck grounds. I'm considering a Holley Sniper EFI aftermarket TBI system but the price tag makes me a sad panda. I guess now I have to go look into what an LS swap will cost?  at 300 bux for the motor, how bad can it be? (what else am I going to need? The entire engine wiring harness and ECU? A megasquirt?)The only thing I'm set on is the Thumpr. I'm happy to change the entire rest of the engine, I just want dat lope

Yes, you'd need the engine, all accessories on it, and the full fuel injection / harness / ECM. No reason for a megasquirt unless you've already got one or are trying to set the engine up without the stock harness / ECM. The GM ECM is pretty thoroughly hacked at this point and can handle just about anything you want to throw at it. You would probably want the transmission to match the engine, too. Seems like '92 could be a non-electronic 700R4 / 4L60, an electronic 4L60E, or a 4L80E. I don't know if there's any "LS" or "non-LS" 4L80Es out there, but there is definitely an early / late 4L60E split. '92 will be well on the early side, any GenIII should have the late version with a separate bellhousing.

Any reason I wouldn't be able to just bolt that to the back of an LM7? Well, kastein, if you're willing to rip all that poo poo out, and TerribleRobot/Adiabatic are happy to shove it all in, I'm game to put an LM7 in - it actually seems like it might even be a more sane decision, somehow. Or at least cheap. (Freakin' LS thumpr is $400... but I suppose junkyard parts are cheap!) Edit: it's worth keeping in mind, too, that Adiabatic has a lift, which helps (especially if we swap the whole engine...) literally a fish fucked around with this message at 23:10 on Jan 7, 2016 |

The more I think about it, the more putting an LM7 in makes sense. And the more I think about that, the more buying an entire LM7'd truck for parts seems reasonable... I'm sure it's not, though. hey ken how do you feel about LM7/harness/manifolds/etc pulling

The mounts and overall length and such should be the same, right? Yeah, I found this that covers some of the details. The GenIII flexplate / crankshaft are at a different depth relative to the transmission than the original SBC/BBC. But I will wholeheartedly recommend just grabbing the 4L60E with a donor engine - you can tune the transmission at the same time as the engine and it is vastly more flexible than what you can accomplish with the 700R4. If the mount for the transmission doesn't quite line up, it's still a truck - unbolt the crossmember, bolt it to the transmission, drill new holes wherever the crossmember lines up and bolt it there.

Those 5.3 truck motors seem to be very long lived.
