I have a '95 LT1 and 4L60E from a Chevy Corvette that I'm planning to shove into a '72 Oldsmobile Cutlass Supreme (Both GM so it's ok) to replace the old 350 rocket and TH350. I'm less worried about physically getting them in right now, will figure that out later, more about getting them ready.

The engine and trans are from a junkyard, who knows how long they've been untouched as I got it from someone else who abandoned their El Camino project.

Is it possible for me to, with no engine building experience, to tear down, replace critical parts CORRECTLY, and rebuild the engine at home, likely in the backyard as shown? If not, I can try and find an engine shop but I'm in a smaller town in Central Coast CA and there's not much here. I'm planning to send the trans to a shop and not try that myself.

If yes, what do I need to swap and what should I avoid? Gaskets should be easy and necessary, but are bearings beginner-friendly? I'm an electrical engineer, not mechanical, but I should be able to take measurements and follow instructions after getting all the specialty tools.

I know the optispark should get replaced, as well as the water pump. Anything else or other VERY easy part swaps that should be done? Nervous about jumping into it and ending up with a now disassembled pile of scrap.
