Engine SwapEverything about swapping an engine into your Third Gen.....be it V6, V8, LTX/LSX, crate engine, etc. Pictures, questions, answers, and work logs.
I pulled a 350 engine out of a 1986 GMC k2500 but I was wondering what information I can get out of this ACDelco tag found on the bottom of the block:
AKA is there any way to lookup the serial/part number on an ACDelco site? I don't know how recent this was rebuilt or how many miles are on it after the rebuild.
The real question is, do you guys think this swap is worth it?
I plan on keeping my tbi intake, as the 350 was carbureted. I really only want the 350 block. I'll also change my trans to a t350.
Additional questions:
Could this engine be blown in the future? or is that a shitty dream of mine lol
1991 rs has an ECM, and I'll be removing the cat because I have new headers and I also plan to straigh-pipe the exhaust, so should I ignore the check engine light or flash the ecm?
That part at least is somewhat normal for a rebuilt engine.
The block might have a future; the crank, not so much.
Looks kinda like the cheeeeeeeeeeeeeeepest possible thing that could be thrown together for high-volume fleet customers who didn't care in the least whether the engine was "good" or not, as long as it got their already mostly-depreciated vehicle back on the road earning revenue; and who weren't willing to spend even the little that it takes to buy that "260 HP" POS (new) that's just a 70s smogger replica. For its most likely target market, think, phone company or city delivery service van.
You're not going to find out how many miles it has on it since it was rebuilt, unless you can find the vehicle it was put in. Waste of mental effort.
Look at the parts it's made out of. What head castings, what cam, what pistons, etc. THAT'S what it is: it's the sum of its parts. Look at the condition they are in: THAT'S .... the condition it is in, as far as how much useful life it has left.
Whatever it is, doesn't look like any kind of "racing" or "performance" or "heavy duty" material to me.
That would depend on what kind of block it is... specifically, 1-pc vs 2-pc rear main seal.
pulled the engine out of a ... 1986 gmc k2500
Doesn't too much matter what its PO had dropped it into; that has no effect on the motor itself. Although, that piece of info is somewhat helpful, as it might tell which crank style it has: the 1-pc was introduced in 86, so it's likely the newer style. But you can tell more accurately by just looking rather than worrying about what came in what.
