Hi everyone I'm please to be there.I own a 70 roadrunner it's a project I work part time for many years now. I need info on the build of a 451, the car is convertible with 4 speed and 3.23 gear.I have what needed for the short block with arias pistons.The biggest part of the problem is choosing the right cam, head, intake, comp ratio,etc.
