    What do I have in my 454

    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.
