I personally only know of one guy who has run the super victor.

It was on a 400 inch 3.79 motor in a 2400 pound tube chassis 70 cuda. basic combo was 13 to 1 compression, ported biba heads, 268ish at 50 roller cam, brake, 904, dominator.

the car is well known to a number of guys on the board here, and the owner really had the car super sorted out. he went a best of around 9.03/05 or so with a victor manifold.More generally high 0's and real low teens

he swapped to the super victor, and was never able to get the car to run any better than a 1/10 slower with the super victor installed.( high teens low 20's) again, this was an extremely well sorted out combo.
Personally, i am yet to be sold on the benefits of a super victor on a " standard headed" small block motor.
maybe there is something out there that it might show an improvement with, but i have yet to see it.

Mine's a 410, 10.8:1 comp, pump gas, 750 carb, small roller (248/254), ported eddys,Air-gap intake...times in sig. Switching to Victor intake, 950 carb this year...maybe a bigger cam too if I can scrape up the money.

i have a little 398 and i personally had the best results with the indy intake over the victor and a 1000 cfm over a 850 with w2 heads max ported at 2775 lbs roller cam 630-650 lift
