What is the rest of the rear suspension going to be???? Trucks are notoriously traction challenged because of the lack of rear weight.... Might also want to consider lowering the truck a bit, maybe as much engine set back as possible. Takes more then just horsepower to build a consistent bracket racer..... If you have to battle wheelspin every launch, going to be tough to keep your ET's consistent.. It's got to be able to hook hard and launch straight every pass, or the amount of horsepower doesn't really matter.....
