Could be in the 300 neighborhood with decent compression ratio. You can boost that with intake, headers, etc. etc. etc. Good heads are the key. You should research the ones you have & find out the chamber size then you will know if room for improvement. Up or down on chambers changes your comp. & you can only run so much.
If the 1969 Cutlass supreme isn't a muscle car, I dont know what is! Starting with the body style; It has that classic mean type "A" body style. The 350 rocket 4bbl was made with 325-340 horsepower STOCK! With just a little tweeking you could get up in that 350-375 horsepower range. Its a beautiful car and the 350 rocket was made for torque. Where as the 350 chevy was made for rpm and solid horsepower. Its just a matter of your personal preference.
Should be right in front of the carburetor, basically centre of the engine, steel pipe going into it.
The 455 will fit. The transmission might have a shorter tailshaft, though.
