Building a Dirt Track Car

Horsepower won't do you any good if the chassis is not hooking, and gearing is gonna have a lot to do with the equation also. We were running a .010 over 350,(GM, sorry) restricted to a 2 bbl carb, roller rockers, and headers. Don't know how much horse we were making but I'll bet it wasn't over 400. The rpm range on the cam figures in also. You want to make you power in the 3-5000 range. We didn't tach much over that. I say horse power is secondary to handling.
