That is awesome!I run Fingers cast pistons. I have 82 1/4mile runs on the motor. 38 of them are in the 9's and 14 of the 9sec passes were 9.4 witch is the fastest I have been. I have been through 3 Allison transmissions, 2 input shafts and 1 output shaft on the Ford transmission. The 3 times my shafts broke my logs show the motor reving to 5800 rpm. At Schieds the converter was not locking so all 7 runs I made the rpm never dropped below 4100 with highest being 4650.
I have about 5000 miles on the street. The tune I drive on the street with dynoed around 700rwhp.
My race tune dynoed over 1100rwhp and at the track I see 84psi of boost and 125psi of drive pressure. I still have the stock Kodiak manifolds and up pipes, so I think I could get rid of some of that drive pressure with some better flowing manifolds and up pipes. I think I'm going to pull the motor apart this winter and look everything over.
