dirt track'in a A-body

How much vacuum does it have to pull ? find the shortest steering arm
that you can for fast steering
What ever you do build ,build it 2thousands loose and ran a 3 speed trany with with the smallest flywheel you can.. did mopar have an aluminum fly wheel ?! ?.
stager your tire size 2 ta 2 1/2'' right sides taller
Heck I have seen to much engine hp is a waist of time, build it to last and don't over carb it.. We have a few dirt track pro's here that will chime in here ........ Nothing like getting on a pile of dirt and racing, very addictive
and fun.......... can you run added weight ? alignment will change per track......... Enjoy.
