Over 75 pulls later, we made the most power using the least amount of fuel (low BSFC number) ever. Sometimes a low BSFC just means you're running on the ragged edge of lean, but we checked the spark plugs very carefully and the dyno's knock sensor never even whispered. Some of this month's extra peak power could also be at least partially attributed to a new proprietary hydraulic roller cam from COMP Cams that we installed. Although it did give up some low-end torque compared to the other cams we've tried, 483 peak horsepower from an 8.5:1 compression, 355-cid small-block is very fierce.
