307 CID Oldsmobile engine
yes
You can put Oldsmobile 350 heads on an Oldsmobile 307, if the 307 is 1984 or older. It will take some work but it can be done, I know for a fact that it can, because my 307 has 350 heads on it. It runs great. I'm not sure about the cam though.
You rent or buy a hoist, undo motor mounts trans mounts etc then lift it over core support without trans or leave trans attached and roll it out the front. This is easiest way, but have to take apart front end
the 307 only had 140hp, only the 442 with the "9" code 307 had 180.
Some do. What year?
Oldsmobile used 307s in those days, not 305s - the 307 had 140 hp

Oldsmobile used to make a 307 V8, but it has nothing in common with a Chevy V8.
