Got a Hp & torque question. I have a 1975 454 block, bored .030, with Forged Dome top piston, 1972 era heads .219? heads. I run a Comp 272 Hydraulic flat tappet cam with roller rockers. Elderbrock Preformer intake with Holley 750 DBlPmp. Headman headers.
Runs ok I guess, and idea of Hp & torgue for this combination. 2 1/4" pipes thru magnaflows.

I don't know if this will help but i had a 72 454 vette and by the shifter was only 270hp and 454tq. and was a ls5. Maybe you can lookup the specs on it to base your engine. If i was to geuss from what you say 350hp and 500tq.
