Don't read if you're close minded

Well, you got me there.

I have run a 4500 on a dual plane, but it was an old BBC intake made for a 4500.

So, no…….. I guess I haven’t done the same test that Eric did.

Though I’ve done it numerous times on single plane manifolds.

Must have been an old Eddie C-454 intake. Would have made a good test piece for this test, with a 4150 with slotted base to bolt directly onto a dommy manifold.
