350 GM crate in 78 cutlass
#2
Do already have the engine? Most of time on these new crate engines they have a flywheel, but not always. The Olds flywheel is different then a Chevy. So you will have to have the correct one. It depends if the engine is internally or externally balanced. On the 85 and back sbc they are internally balanced [except the 400]. The 86 and newer sbc are externally balanced. They still make both for crate engines. So if your engine doesn't have one you will need to know if your engine is a internal or external balanced.
Other then that brackets you can get at junk yard cheap. You will need chevy motor mounts. You can either modify the wiring or replaced it. If you keep the A/C the hose are longer on Chevys the compressor mounts on the driver side of the engine. The power steering pump bracket is different so you will need to replace it. Exhaust manifolds are different also so the downpipes are different unless you go with headers then you need ones for a 78 Monte Carlo.
I guess you already have a V8 so that is most of what you need. If have the Buick 3.8 V6 you will need a different fan shroud and run new fuel lines for the correct side of the car for your engine.

Since the engine doesn't come with a intake and harmonic balancer the same info applies for them as well, being the older style engine.
I have never used a serpentine setup before so I not sure what would or wouldn't work. Maybe one of the others people on here would know for sure. I do know that your brackets and pulleys have to match no matter what setup you go with.

Ok, you know about the mounts and the starter. You mention flywheel? You will need a Chevy flywheel. As far as swaps go this is both an easy and common swap. Good luck with it.

Sorry, but since I'm a member of that forum also, what are you referring to? OP.com is as committed to oldsmobiles as this site is. Maybe not as diversified, geared more towards g-body olds, but still in the family.
