Cross Rams and Tunnel Rams, Buddy Bar

The best thing to do to fix that intake is to make a 1 inch spacer to raise the top plate away from the floor. The carbs are way too close to the floor of the manifold.

I suggest 1 inch because much more than that and you won’t be able to close the hood, which defeats the purpose of that intake. 2 inches would be better...but the hood thing crops up.

Unless you have a six pack or super stock scoop, of course. But I'm curious how raising the plenum that would affect overall rpm tuning with that. Would it add so much volume that volume would have to be decreased elsewhere in the plenum to make up for any loss of low rpm torque or would it relegate it to a 4500 rpm and over power band?
