340 Intake Manifold Casting# 2531915 - Upgrade

I am leaning toward buying a Performer RPM, non air gap at the moment after reading the article were Dave Hughes tested a bunch of intakes.

Should knock at least 25 pounds off the nose and like previously mentioned it will roast the tires with whatever intake it has on it.

I liked the fact that the Performer RPM only has 16 cfm difference from best to worst runner where other intakes were as much as 40 cfm difference.
