Getting the Intake on Intake Manifolds
You must remember,
Each Intake Manifold, will perform differently with a selected Camshaft.
On an 'even' keel test, the
* Edelbrock Performer Air-Gap #7576
* Holley Strip Dominator #300-8
Were identical in Horsepower output at 6200 RPM's.
On a 'Sour Note', most everbody was not impressed with the original Edelbrock Torker 340.
