I'm still working on getting the kinks out of the motor. Spitfire Headers are coming this week. The 833 that is in the car is a little tough to shift. It needs some adjustments that I have not gotten around to yet. I like the 3.23s for the highway but my cam needs more gear. I have another 8 3/4 with 3.91s that I'm going to swap in later if this car becomes a more serious street/strip car.
