Mr. McFast:If properly tuned,425-450 HP is not out of reach.However;Your stall is too low,and I'd recommend at least 3000.For a rear gear,at least a 3.55:1,and definitely posi.And as for the fuel pump,are you using a regulator?It should be set at 5-7 psi.As for E.T.,what is the engine in,and what is your race weight?

I would guess around 400 HP and 420 lbs of torque, do you have access to a chassis dyno in your area? The track will be another way to check your HP and torque, I think if your getting low 13's-high 12's 103+ MPH 415 HP plus for sure.
