gm makes 2 different 5.0 engines. one is a chevy 305 which is interchangeable with a 350, 327, 283, 307, 383 or 400.

the other is an oldsmobile 307, an olds 350 rocket will drop right in, but i dont think you are talking about that engine.

chevy has its own bellhousing pattern and buick, olds, pontiac, and caddilac share another. some transmissions like the 2004r have both patterns.

so to swap a chevy 350 in place of an olds 5.0 (307) you will need the engine, frame motor mount brackets, and transmission. the exhaust will also be different. depending on the model of trans, you may also need another driveshaft or have yours shortend.

:biggrin: just find a olds rocket motor to put in it if you put in a chevy 350 the bellhousing won't fit up to it. Also if you are thinking about changing the tranny to say a 700r4 you have to cut the driveshaft down because the tranny is longer than the original one. my advise get a rocket 350 and a B.O.P.(Buick, Olds, Pontiac,)turbo 350 or 400 tranny

GOOD LUCK BRO! :biggrin:

Not really, you put chevy motor and frame mounts on the new chevy engine, drop it in place, mark the holes, pull it out then drill the holes for the frame mounts/mount them up and drop the motor back in. If you use a TH350, it is vacuum modulated and no lockup/wiring to worry about....battery/starter wires go on the passenger side, coil wire is the same, and everything else just use a full size chevy (caprice or whatever) if you need parts (radiator, hoses, etc) Its not really that bad :cool:
