I have 9to1 pistons will need an intake four barrel and cam heads does anyone have any ideal on which set up I would need to get to the horsepower that I am looking for
As for a cam, you could probably select a stock replacement for an earlier muscle car and be at the top end of what you're looking for going this route. This is actually the cam that I run in my car with 1.72 rockers and Trick Flow Twisted Wedge heads, and my combo produces 265 rwhp. I'd suspect you'd see something similar, albeit lower, with everything I've linked this far.
You'd probably want a carburetor in the 600-650 CFM range and you'll have to find a set of headers, but this stuff should meet or exceed what you're looking for.
