What exactly is the right combo for the .484? Most guys I've seen are running 3.91 gears. Will it work with 346 heads?
My only concern is the torque side. 71' Roadrunners weigh roughly 3800-4000lb so that's another factor.
the 474 would be better for your application. As for what do you need to make the 484 work...compression, decent heads, headers, stall (you have pedals so no big deal there) and at least 3.91's especially in a heavy car.
