...as I went through a few years back while racing offshore powerboats. The configuration was 4.060 bore and 3.5625 stroke for 369 inches (class limit was 370).
We blew through the walls of two different 350 4 bolt (aka 010) Chevy (sorry) blocks during the course of one season. We were making about 650HP and the stock blocks simply couldn't take it. Luckily Chevy (sorry) had special "BowTie" blocks available from their NASCAR program. The only real difference between the BowTies and the 010s were the thicker walls .
FYI, the measure wall thickness on the 010 blocks we were using was in the .140-.160 range.
Cheers, Dan |
