Chevy 355 Small Block Engine Build - Cheap Skate!

The Comp solid flat tappet cam measures 255/263 at 0.050. Since the flat tappets limit lift to 0.540/0.534 inch, the School of Automotive Machinists (SAM) says a solid roller cam with similar duration figures would yield an additional 15-20 hp. However, the flat tappets are less expensive and provide excellent durability. To keep rpm from exceeding 7,000 with a budget short-block, the lobes were ground on a relatively tight 106-degree LSA.
