an offy w/ twin 600cfm edelbrock 1405s or an sp1 with?? id like to know if i would get better performance with one over the other, i have the parts listed but need a 4bbl for the sp1, was thinking bout a 1050 or something, 72 455 track only, big valve heads, headers will be on it, will need help choosing cam setup, that would be the only thing left to do i think, thanks john.
they say that the offy needs work to get max performance out of it. some welding work etc. the sp1 is a good choice.
