Have a friend with a 72 race chassis Cuda.
Been in the 7’s currently with a stout big block in the 1/4 on motor. Car is very light.
Years back he had a b1ba headed small block stroker in it. Ran 9.06-9.07 best maybe couple hundreds quicker, but consistently right around there.
Took his Victor 340 off, installed a stock Super Victor. Car slowed down a whole tenth. Think the night I saw him test it, went 9.17.
Moral of the story I guess, those things need worked to shine. Guy I am talking about never followed up doing that to the intake. Put his original intake back on, then not long after went dark side( big block)
Black Cuda, well known in these parts.
