I put 2.25 intakes in my Edelbrock Performer RPM heads and they flowed 341 cfm @ .700". The little 451 stroker made 534.9 lb-ft of torque @ 3,500 rpm, 574.0 lb-ft @ 7,200 rpm and 786.9 HP. Oh......all motor, 11.7:1 on 93 octane (the 10% ethanol stuff). Runs fine on 91 octane too.
Pump gas eddie headed 451? Pushing 800 horsepower? I say b.s.
