Does it matter Brian ? Two of 3 cv type heads are racing each other and most rather chat about and deflect attention to that aspect.
We have choices and shouldnt be "shamed" for not choosing the "popular" one.
If it doesnt fit a bow-tie, blue oval, or pentastar it shouldnt matter.
Pick your favorite(s) and do what you want with it. Someone will always come along and one up it eventually.

#62 D ports went high 6.90's in a door car 23 years ago. Same car/motor(406 stock block) with E-heads never bested that ET. Iirc it showed more mph. Took quite awhile before E-heads(wide ports no less) in a door car went sub 7's and bested the mph.
Ever wonder, how much further ahead we'd likely be, if we spent as much time improving our programs as we do bickering over bull crap???
Hope both have a clean race.
