I run a completely untouched Super Victor. When you look down the plenum, the head ports line up about perfectly hence left it untouched. But I'm sure some roof blending and runner entry work would benefit it. Someday!!
Reason I say that…..
Good local buddy has a bad arse black 72 Cuda, super lightweight chassis car.
Currently runs high 7’s/ 4.90’s with a stout big block.
Years ago he had a small block B1BA deal in it, roller, etc.
Well scienced out, ran 9.04-9.07 all the time with a Victor.
He swapped a super Victor on it, slowed down to 9.15-9.17
