Stock intake vs performer?

Check out Vizard's book "how to build horsepower" (?) he massages a stock 4bbl chevy iron 350 intake and makes it work better than ANY aftermaket intake on a stock 350...just a die grinder and a little cleanup work. Induction on a stock motor is pretty forgiving, but the Edelbrock is probably 60% lighter. Most stock Mopar 4bbl intakes are of a very good design.
