Re: 350 SBC HP Guestimates.

Based strictly on the parameters provided, Engine Analyzer 3.1 says 462 HP at 6,000 RPM and 454 lb. ft. at 4,500. This may a bit on the optimistic side, but should be fairly accurate. I would think 425 is a "slam dunk".

One word of caution. The compression ratio of 10:1 is a bit on the high side for 93 octane gas and iron heads. Detonation will occur between 2,500 and 4,000. I woukld recomend dishing the pistons to get the ratio down to 9.5:1. You'll give up about 7 HP and 6 lbs. of torque. Hardly enough to make the fuel issue worthwhile.
