Thats the comp. cams 264 cam. Good cam.In a 350 I would say 280-310hp.This is just a guess. Maybe 240-270hp in a 305 but that might be way to high.Any of you guys with 305's want to throw some numbers in?
Sorry at the rear wheels. 210-235hp.

Transmission: T10, hurst shifter
Axle/Gears: 10 bolt, true-trac, 3.73
ported heads, 210/220 roller cam, 10:1 CR, i'd say higher. Almost 300HP is my guess.
I'd do some porting on the intake if you haven't yet, that's the restriction on a tpi motor IIRC.

Sonix, I ported the intake big time and I do not just mean port match.
I am thinking 245/325 at the rear wheels.
I will be finding out.
the car is not built for racing but I still would like to beat up on the 5.7 GTOs and then tell them they got spanked by a 305
