Joe's motor had about 1000 miles before the dyno pulls. His Cobra has the standard SPF 3.73 final rear axle ratio. The car has a Tremec TKO trans with a .68 5th gear. I custom built the throttle linkage to give a linear pull with a little longer travel. This was done to avoid the "hair trigger" throttle that can detrimental to traction in high horsepower, light-weight cars. Surprizingly enough, if you roll into the throttle the tires are able to keep up with the engine revs resulting in a small amount of wheelspin. If you stomp the throttle, expect tons of wheelspin and bouncing off the rev-limiter.
