Vortec 5.7 is basically a bolt in for a gen 1, right?

if true 85 trans parts its 32 spline and hydro clutch . would be a 208 tcase unless newer and then a 241 and thats a keeper .

It at least looks like it was originally a manual, based on the formed hole in the trans tunnel, but the rear of the hole looks like someone literally just got in there with a pair of pliers was ripped the hole open bigger...that's why I was thinking the transfer case was a swap in. Of course, until I look at the RPOs and numbers on the parts themselves, I won't really know. But hey...even if it is a 208, then worst case scenario, I have a spare for the case in the K5.

With the rear end being a 14B SF, and a very hacked in exhaust system, I'm betting that the truck is a light duty 3/4 ton, with a 350 originally in the engine bay...so again, until I run the numbers, I can't even be sure that it's an '85 454 either.

Definitely looks like a towing engine.

It has the old style smooth valve covers with the rounded top...I doubt it's an L19 either, lol. Much more likely to be an earlier motor...probably out of a motorhome or something. Still feels stronger than the 350 was though, and that's good enough for me for now.
 
It that one tooth on the bottom, one on the top, or another configuration?
 
Presumably the two remaining teeth on the meth heads.
