Older 350 in 91 Camaro
Alright guys I have a 1991 Camaro RS with a 305/700r4. I have a chance to get a built 350 out of a 1972 El Camino SS. They tell me it's the original engine minus the tranny. Can it easily swap into my RS with minimal difficulty and bolt up to the 700r4? I also got a rear end out of a 1995 Z28 auto. Will that be sufficient enough? I'm tired of the insanely slow 305 I have now and want to upgrade. Is it really a good idea to put an engine that old into a 90's car? Thanks for the input.

Assuming how badly you want to put it in, you can get anything in that size range will fit, you just may have to work at it depending on how things go. It should bolt up fine to a 700r4. and the Z28 rear end should be enough as well. the wiring will be the fun part. that'll be the most difficult part by far.

I helped my nephew put the original 350 out of my 71 in his 87 Z years ago. Problem 1: the dipstick hole being on the opposite side, so it was blocked by the exhaust manifold. Problem fixed when he went to headers. Headers also fixed one of the exhaust bolts not being able to be used due to bolt pattern on 71 heads IIRC.
Problem 2: TV cable hookup with new carb setup. Told him to get correct aftermarket bracket, so TV cable could be properly adjusted, not to drive it till then. He didn't listen, tried to mickey mouse original bracket, burned up the tranny. Problem fixed when he got right bracket... and paid $$$ to get tranny rebuilt.
Those are only issues I can remember, other than that, bolted right in.

If its a daily driver stick with a fuel injected motor, if its a weekend toy to burn up assphalt then go carbed get a TH350 or 400 and go have some fun.
As you can see I didnt much care for the bad fuel mileage of a carbed and went with a 4th Gen.
I had a 86 IROC with a built 355 on a 750 carb. Ran faster than my SS does now but you couldnt go very far on a tank of gas.

The '72 engine is a flat-tappet cam, so you'll need to buy special engine oil with the right additives so you dont wipe out a cam lobe.
Also, the '72 engine uses a 2-piece rear main seal to hold the crank, so you'll need the 2-piece seal type of flywheel. Your '91 engine is a one-piece seal and the flywheel will not bolt up.
I think its better to use a newer 1-piece, roller-cam engine, but its your choice.

Keep the 700R4 since theres nothing wrong with it, no sense swapping to a Th350 if theres nothing wrong with the one you have.
Kevin is right, you'll need to buy a different flywheel.
You'll also need to buy a torque converter lock-up kit to keep the trans from burning up.
