We had previously tuned this track car with his old set up, a TSP 408ci with an MS3 cam. Unfortunately one of the valvesprings broke, wreaking havoc on the block. We replaced it with another 408ci, however on this go-round we added our own custom cam, picking up 30hp over the MS3. We also installed our Brian Tooley Deluxe Cam Install Kit to prevent the same thing happening again, and a Melling 10296. The final numbers were very stout, at 516 rwhp & 470 ft/lbs!
