Yes Roger, the diameter is a huge prolem and I will not grind on the intake! There is a connecting piece that passes in front and en-circles the whole dizzy. So an offset drive won't work. I may have to "clearance" the dizzy body or find one that sits higher. The narrowest body I've found so far is 3" and that one is an old mallory and still hits so the unit won't sit on the block. It comes very close but I'm not there yet.

We'll keep searching.
