Just got my 440 with the Edelbrock RPM package finished and put on the dyno. Edelbrock said it would make 469 Hp, I got 484.1 HP. I changed carb to a Holley 850 CFM, Got 500.9 HP at 5600 RPM. Edelbrock said it would make 515 foot pounds at 4000 RPM, I got the same thing. With the Holley carb I got 535 Foot pounds at 4000 RPM. Edelbrock did there homework on this RPM Package. :cheers:
