Hey Guys, downloaded the Comp Cams CamQuest6 program and was playing with engine combos and was wundering if anyone knows how accurate this is to an actual dynoed engine?

Looking to build an aluminum headed 355 or 383 sbc for the street.
Did notice a big difference going from hyd. flat tappet to hyd. roller cam.
Rollers are of course more money but more benefits and output.

Any feedback on this program?

Thanks.
