Aiming for a specific HP number is sometimes a bad thing. You can do more with less as show by 70aarcuda. The draw backs are a bigger expense to do a stroker The strokers create a lot of torque and lower rpm ceilings. But the power comes in earlier. The need for a bigger head to expolite the HP potential can cost a good bit. The Edelbrock head can in stock form run in the 11's if the rest of the car can help it, not hinder it. The cars weight, chassis strength and suspension set up alone with the gear ratio and etc.... Is more race like than street driven everyday ride.
