We just put in a 455 H/O in a 80 Trans Am and I was wondering if anybody is a good guesstimater for HP and E/T for the car

The Engine is a 455 H/O .030 Over, Forged TRW Domes, 7F6 RD Port heads which have been ported, Hooker Super Comp Headers, Holley 850 DP, Torker 2 Intake, HEI Distrubutor with 50,000 Volt coil (soon to be upgraded), the cam is 247/255, .525/.540 lift

Its a 4-Speed

The Car is full weight which is about 3600


Any Guesstimates?? Im thinking maybe 600HP and 11's

I would say 550 horse, mid-to-low 11's. If memory serves me right, Pontiac engines don't respond well to domed pistons. But, I might be thinking about Chrysler RB engines (440's). But, sounds like it's mean. Good luck!! Race gas 24/7, though!!!
