Performer RPM will show a 30-40 hp increase over a standard Performer, FWIW.

i think you may be close, my guestimate would be around 340hp/400tq, i think this motor may benifit from a little larger duration and lift on the cam, plus what Tech1 said with the RPM intake.

Yep, the larger runners and straighter shot at the intake ports on the head along with a good set of long tube headers will go a long way toward lettin' the motor breathe.
