Hi, i need some advise, I bought stock 73 400 sb with about 60,000 miles ten years ago. The parts that i put in this motor are, 272- 454 lift cam,lifters,valve springs,hirise manifold,750 carb,1.5 inch headers, Hei distributor,timing chain. The car has a 350 trans, 8.2 10bolt rear with 3.55 gears. This is a street car that i bring to the track about 3 times a year,its best time is 13.60. I bought a fresh set of 041 heads with 1.94 valves, will my compression ratio be to high with my stock pistons. Thanks.
