I think Ehrenberg did a series in Mopar Action with a 500 cubic inch wedge. This was a 1969 Roadrunner. He was running 2.94 gears, and a Turbo Action Hemi converter. I believe the car was running low 12's. The big inch engine has so much torque it is easily able to overcome the tall gearing and the looser converter allows some rpm's at low speed. I run something similar to this in my 1968 Charger. While I don't have timeslips, I can tell you this is a fast combination and is very sweet to drive on the highways.
