Hello! I'm a new member looking for some advice on cam choice for a blown BBC, around 470 ci, 8;1 comp. th400 trans, 3.50 rear end, about 2400 lb car ( 32 Ford ). Car will be street- driven. I want to go with a roller, for reliability. I've built many carbureted small- blocks, but have no experience w/ big- blocks or blowers; any thoughts?
