I have a couple different questions, im trying to figure stuff out. What would be the approx. cr of a 455ci with 114cc heads and flat top pistons. How much would the cr raise if I stroked it out to 474ci with same heads? I think it would be bad ass to have a blown 474 stroker, but i wanna be able to run pump gas(i will probably only boost it like 6psi). any ideas ponti-action racing makes a 474ci stroker kit for like $2k. anyone know if its forged, doesnt say on the site, but for $2k im assuming not. But it should hold up to only 6psi.
