Mill amd blend the devider at 1,2,7,8 for more equal fuel distribution,We usually cut them back 1/2" or more.

My low deck single plane is off my motor for the winter. I wish someone would test it against a box stock intake to see if it's better or worse.

Plunge cut it from the top to the floor and radius and blend the edge.

This is a brand new 440-3 I bought about two weeks ago.

Yes, low deck 4500.
It has been opened up alot and performed very well years ago on a nitrous motor that went 8.40's in the 1/4. I just always wonder if it is helping or hurting me in a pump gas high 9 second N/A combo.
It has a steeple shaped piece in the floor if you can see it in the photo.

I would also love to trade it for a low deck Indy tunnel ram, preferably with a single carb top. My intake is now powder coated in black chrome and looks awesome. But anyways, is there a way to flow test an intake manifold for comparison?
