The job of an intake manifold is to evenly distribute the air and fuel mixture supplied to it through the carburetor. A general rule is that the more air and fuel you supply an engine the more power it will produce. An intake with good air flow will out perform a stock one. Intake manifolds can also help give you the classic hot wheels look, if that’s what you’re looking for. There are thousands of manifolds out on the market trying to take your hard earned cash. A good plan would be to stick to a big name brand, such as Holley, because you know the part will be built with quality and will usually last as long as your engine. A good intake can open up new options for carburetors, the final step to completing your power upgrades.
