how much HP do you guys think i'm cranking out read the sig & the heads are stock castings with a mild port & polish

 

Hrmmmm, Just a guess but I would say 400-430?????

 

350rwhp

 

more than stock i would hope

 

I may be way off, but, a 383 with 12:1 compression and mild ported heads, bigger injectors and throttle body, cam, tune, and headers. I would guess the 450hp area on the motor. Long tubes 1 3/4" headers would really improve the numbers over them short small tubes on that combo.

 

Are those the heads from Golen?? Cam lift means little compared to duration numbers because duration dictates rpm and hp is torque at rpm.
His 440-480hp strokers are known to dyno way down in the 320-330rwhp range.
