If you go to Hughesengines.com they built a 580-600hp 360 with both intakes & I got the impression the Victor was superior. The Mopar had been modified.
Which is superior? I'll go with the newer Victor intake over the older M1.
I knew a guy that picked up a couple of tenths with the switch to the Victor.
I think it would depend on the level of the engine build. I'm sure that the Victor has a bigger plenum and would work better with larger and/or higher rpm engines.
