manifold swap


bustoff

Recommended Posts

I have one on my big block also.  I'm running a holley 750 carb and a 4" open element air filter.  The air cleaner base has a 1" drop center and it looks tight to the hood, but I never measured.  I would be very careful with the first hood closing if not using a drop center or a taller element. You'll like the intake, it's a very good, does everything well, manifold.

I'm running the air gap rpm as well with a drop base and a 3.5 element.  No issues.  The 3.75 element would barely brush against my hood with no hood insulation.

 

For my hood clearance test, I take make a loose ball of tin foil and put it on the air cleaner (play doh works too) and close the hood to the first latch, make a visual inspection, then close all the way.

 

I love the WIX racing filters as you can get them in 1/4 inch size differences to fine tune the biggest element that will fit under your hood.
