Indy 416 ,686 roller cam, 456 gear, 29 x 14.5 hoosiers 0n 15 x 12's ,tight 5000 stall, shift light set at 8000. rev limit set at 8500. Have a hard time obeying the shift light. It keeps pulling hard. I bounce it off the rev box once and awhile . Its my sons and I take it out when he's at work. This thing is a wild out of control steet car with no power adders. I asked my son how it pulls , When he came home with it one day. He say's it pulls hard but nothing like being planted to the right rear corner of a sprint car for 25 laps. The tail pipes are tied into the 3.5 dumps in front of the rear. We had to leave the tips on. This was made possible by cutting 3 inches out of the right side of the factory gas tank.
