Crane CCH-312-2-NC
72 Duster, 10.5:1 440, 915 heads, 833, 3.91, 26" tire.
It was built when it was an auto with a 28" tire and 3500 stall and was a bracket racer.
Runs and drives great now, but lugs a bit and loads up under 2500 rpm. Trying to drop my highway cruise RPMs a bit, but not sure the current setup will work with around town driving then.
