intakes

I have one on my 360, can't say how it performs against anything else since I built the engine with it. My engine is making approximately 370 HP (based on 1/4 mile times) with it and the engine runs strong from 1500 to 6500 rpm.

Hot Rod Magazine did an economy build on a Chevey 350 and used one. The engine produced over 400 HP.

People call them a clone or a rip off copy of an Air-Gap but other than using the open plenum design they are as different as any two of the same type manifold for the same engine can be. And yes Summit is selling them under their name.
