not eactly you will need a transfer case
No
Not from the factory.
will it bolt up to a700r4 transmission
As long as it is a B.O.P. transmission, yes. It will not bolt up to a Chevy engine without an adapter plate.
The 305 was an option on that car, so a 350 should be a bolt-in.
Yes...you can put just about any engine in anything with the proper skills, time and money. If the Cutlass you have has an Olds engine in it now then the transmission will bolt right up to the Pontiac engine. If it's a Chevy engine you'll need a B.O.P. transmission. You will need to change the motor mount location. Depending on the year of the Cutlass it may actually have the bolt holes drilled in the frame for the Pontiac engine mounts. For reference, find an older Grand Prix with a Pontiac 301 engine. This will have the correct mounts and location. You will also have to change the exhaust head pipe locations.
yes.
Need to know which engine and which transmission.
GM never made a 450 tranny, you probably mean a turbo 400 tranny and yes it can be done.
Yes, an Olds 350 will fit if it's the rear wheel drive Supreme. It is the same basic block as the Olds 307 c.i. engine that came with some Cutlasses. Another option was the Chevy 305 which of course is the same block as a Chevy 350 (another possible option) if you are so inclined. An Olds 307, 330, 350, 403, or even a 455 will fit. The 455 will be tight and will need specific headers for the exhaust. Any Buick, Olds or Pontiac (BOP) will mount to your current transmission. If you go with a Chevy block you will need a adapter plate or a Chevy transmission. v6 and v8 engine mounts are different...so you will also need to change them
no you dummy
