Dual plane intakes

I was researching a Comp cam, and the one i have chosen says it works best if you have a dual plane intake. What exactly is the difference between a dual plane and a stock 4 barrel carb intake? Or are they the same and my rookie engine building skills are showing.

as far as I know a dual plane intake has like 2 levels to it, when you look down the plenum it should be divided in 2, one side will not go down as deep as the other, thus it has like 2 "levels" or "dual plane" I am pretty sure that is what it is, or maybe I am just a rookie that has no clue LOL

hope that helps

Ean, you are right, and so is Dubie.
A stock intake is in fact a daul plain deal, but a new aftermarket one will make a noticiable increase in torque.

Daul plane intakes are designed to maximize intake runner (tube) length for better bottom end torque. Single plane intakes have shorter runners to maximize top end horsepower...least that is what the 'ole engine design manuals say.

This is also true.
In the real world of stop and go, there is no reason to have a single plane intake. The performer is a great stock replacement (and boosts power at all levels) and the Performer RPM is a great one for an engine that is a little more on the upper end, while still making good numbers down low.
i have run both these intakes on both types of engines and highly recomend both. Just remember to match the intake description to the cam descriptions.
