I'd be really suprised if you don't push more like 310hp at the wheels.
The stock heads, even ported, will hold you back, but the rest of your combo looks pretty aggressive. The F-cam really needs some good heads to shine, but ported stockers will do the trick for budget reasons.
If you were to have an E or B cam I'd expect you to make around 350 at the flywheel.
I'm sorry Killercanary but if your friend is powershifting his way to 13.5's with that combo, something is seriously screwed up. I notice you didn't put anything down about him having head mods. If he doesn't have any mods to the heads, like porting at all, he's got way to much on the intake side of things. I'd expect an '89GT with freebies and gears to be in the high 13's with nothing else. With intake and a cam of that type, assuming he's got some form of headwork so it's not mismatched badly, he should be in the high 12's at least with those mods.
