Hell Mercury Marine did it. All of the peanut port headed 5's and 6's came with Mark 4 cast iron intakes. You talk about a port mismatch.

I didn't consider or ask about ports, just thought he was asking if it would bolt on.

That port mismatch deal has been the subject of discussions for years. I personally ran a rectangular port intake with oval port heads on a flatbottom I had years ago. I had guys telling me there was no way it would run.............right up until they saw it.

Yeah when I unbolted mine from my '97 Gen 6 I could not believe the mismatch but hell at 300HP out of 454 cid its not a big deal. We also use to bolt on the square port intakes on the Oval stuff in pull truck stuff. I agree is didn't look good but they ran.

I don't mind a little mismatch in the floor area. .. I think a little "tumble" is good.
