    My buddy has a 87 GT with..... GT40 Upper/Lower, Windsor Jr. heads, E-303, Mac Longtubes Off Road X-Pipe, Bullet Mufflers, 70mm TB, BBK Cold Air Intake. He is having it dyno tuned at Houston Performane, can this set-up break 300HP?

    is the GT40 ported?, if not he won't make 300RWHP, he might get 250-275
