I have a stock 440 motor. I have a original cross ram intake 3447 carters. and 286 stock heads, and max wedge repro exhaust manifolds, stock stamped steel rockers. What kind of power can I make by bolting this stuff on my motor? Will I be able to run pump gas with an additive? If I rebuild the motor what cam and pistons would be a good choice.I know I would buy forged ones. thanks in advance.
