no Bryan,...nobody in stock runs that... You can run it in SS.

I do, I owned one. The Cleveland intake that it attaches to has runners that aren't nearly as long as the FE so the adapter has to make some fairly abrupt bends on the end cylinders. Fast guys were taking a Ford tunnelwedge 2-4bbl. intake and making a 1-4bbl.intake out of it like Holbrook, but $$. The Edelbrock Victor for the FE pretty much killed any thought of this adapter being used.

Welp, looks like 2020 will be the final year for us!

Correct me if I'm wrong but if you angle mill the head at an extreme angle thereby reducing the port volume and NHRA only measures the head port volume aren't these "spacers" allowing larger cylinder head port volumes? It's not really about adapting different intakes but using the "spacer" to raise cylinder head port volume as the head isn't measured with the spacer installed. I guess the port entry can be raised also. Seems like a reasonable rule change to me. Although I feel for those affected, anytime you push the rules you put yourself in a position to have the rules get tightened, not in you favor whether it's been accepted before or not.
