Greeting from the Hot Rod Power Tour in Springfield, Missouri. I had a chance to get up on the dyno on sat. In street trim as I drove it in, she layed down a best of 350 hp, 430 ft.lb. of torque. At 17psi with an ambient temp of around 90 degrees. So I'm pretty happy, BUT.......judging form the combo below what would it take to make an honest 400 hp in street trim?
