Ran them several different ways, but I must admit the damned best one was an other wise stock 360. 8.5:1, 340 intake, Thermoquad, headers. Cam degreed in at 110ICL like the card said. That car ran 13.90s with 3.23 gears and 13.40s with 4.10s. I drove that car every day for a couple of years. It was a very fun car.
