edelbrock 2PSP VS performer

caferacerx,
well, it's all relative! I can't compare unless i have a reference... I've got a wimpy stockish 318 - no way for me to know if the performance i have is limited by the intake unless i swap intakes and either make a seat-of-the-pants comparison (not very quantitative) or better yet do a dyno/track run (prob not gonna happen).

I've got stock 318 large chamber heads so i know my compression sucks. Have a set of 302's that will eventually slap on but at that point do i also swap the intake to a performer? Problem there will be how will i know what made me make more power; the heads or the intake or both?

That's all my original post was asking: if anyone had made just the intake swap on a stockish low cube motor for street use.
