its a little high, give it about a 5% variance in actual power. built an engine i know with the specs and i know wut it runs, dynoed out at 144 hp and 162 lb/ft. the comp cams gave it a 152 hp an 166 lb/ft with the same setup. remember this program doesnt take into account the air temp or nothin. its close, but a dyno gives REAL numbers.
