Fuel is 110 Octane, No Idea on RWHP. TH400 4.10 gear, Gonna try the converter I had behind my olds motor, but I bet I will be sending it out to get redone.
The cam was spec'd out by BTR.

Track Results: After working thru a couple bugs i got out to test. 7:16 at 96MPH twice. Same Converter that was behind my 400HP olds motor. Transbrake wire broke so I was footbraking Shifting at 6400, which I need to go up probably to 6800-7000. Need to play with shocks and tire pressure as it is spinning on the launch.
