Don't believe what all of these aftermarket companies claim for their horsepower #s. If that was the case I'd have a 450hp motor...when in reality I may be pushing like 320hp. I'm sure the motor was tested with headers, right. Shorties I take it. Long tubes might give you 5-10 more horsepower...but I'm leaning more towards 5. The rockers won't give you much. Realistically probably another 5hp. As for the intake...8hp sounds about right. So my guestimation would be you could pull another 15-20hp out of the motor.
