My new Cheetah has a 6.2 Bravo One, which for old motorheads is a stock bore 350 Chevy with a 400 crank which yeilds 377 cubic inches. It looks like a SBC, other than some Mercury Marine stuff on it. The question is, what version of the SBC is it? Can I get some Harland Sharp roller rockers and throw on it like every other SBC, or is there some special high-zoot rocker that's required? Will aluminum rockers hold up over time in the marine "always on" environment? Or, should I step up to the investrment cast steel rockers from Competition Cams? Will I see any results from a change like this?
Thanks!
Mike
