YES, It is done all the time. You can put it in a go-Kart if you know what you are doing. That is an EASY job to do on that cutlass.
No
Not from the factory.
The 305 was an option on that car, so a 350 should be a bolt-in.
not eactly you will need a transfer case
No
yes
As long as it is a B.O.P. transmission, yes. It will not bolt up to a Chevy engine without an adapter plate.
A 350 Oldsmobile engine has a different bolt pattern than the Chevrolet engine. The 350 Olds and 350 Pontiac engines have the same bolt pattern. The 350 Chevrolet and the 350 Buick engines have the same bolt pattern. Unless you have a dual bolt pattern transmission (there are some out there) in that Chevy, the Olds engine won't bolt into the Chevy transmission.
Yes, but the exhaust Y pipe from the 305 may not fit the 350.
