IMO, you've changed too much of the stock pieces that work really well. Good luck.
the motor put down 819hp and 756 ft so I know the power is there and its a nos motor
I think the truck should have more upward travel on motor than it does using the foot brake. It use to 1.49 60 foot with a cast headed 461 in it and now it has a little lighter front end,alot more motor and aluminum heads(lighter).
I know its all about dialing it in just going to take some time and help from you guys to point me in the right direction.
