Default '89 Engine into a 75...

What do I need to watch for in doing this swap? I can get an '89 engine dirt cheap to replace my tired '75's engine...

Depends on what your looking to do,which motor are you looking at?Some later motors dont have a provision for a fuel pump,so youll be stuck with adding a electric pump.Also the center bolts on the intake the angles are different but you can drill them out and install a older 4 barrel intake on it.

From what the person tells me, it was in a Camaro. The engine was originally out of an '89, unfortunately he didn't know if it was originally in the Camaro, or out of something else.

He mentioned the fuel pump, it has the mounts for that, but he wasn't sure if the cam had the lobe for the fuel pump. I knew I'd probably need to change the cam. It needs an intake and carb anyways, so thats not a huge deal.

Is it a TPI (fuel injected) motor?

I don't beleive it was. The person selling it (sisters husband) says it needs an intake/carb to be complete.

Make sure it's a 350 and not a 305. A lot of LG4 305's went into the mid-to-late 80's Camaros. Put out about 180hp. By looking at the outside of the engine most would not even see a difference.

I would hunt up the TPI to go with it. Lots of people have done the swap including me. Should be info in the archive or at http://www.corvettefaq.com Other than the fuel pump issue for a carb setup and a different flexplate/flywheel for 1-piece rear main seal motor it will go right in.

Took the words right out of my mouth. I have had a few friends get REALLY burned with this. Most people can't even tell. Typically the Harmonic balancer size is the only clue.
