Air flows: Street Dominator & Edelbrock RPM

Air flow for the three 440 RPM intakes we had around here.

1) OOTB, self explanatory.
2) Pop's is one my dad did 'bout 20 years ago, gasket matched and blended in about two inches.
3) Dyno tested is the customer's that was repair welded and gasket matched for a couple hundred bucks.

We dyno tested Pop's against a gasket matched and blended Torker II on a 496/440 and the Torker II made 612 lb-ft @ 3,600 rpm/638 hp @ 5,900 rpm. Pop's RPM made 640 lb-ft @ 3,700 rpm and 627 hp @ 5,700 rpm.

The Street Dominator:

1) OOTB
2) Gasket matched and blended
3) Quick port to raise lower flowing runners. This gives you an idea what the Street Dominator could be ported to. We took the three lowest flowing ports (#'s 3, 6 & 8) and did a bit of porting on them.
