my stage 6's are MW & i'm using a Super Victor 440 manifold with a Dominator flange but have a 950 Quickfuel dual pattern carb.
This is a little more than what you're planning but for my application this is a killer combo. Last weekend with only the primaries on the carb activating, we pulled a 10.7 1/4 mile out of it. I'm trying to slow the car to run in our 11.00 second street class but the engine is not having a bar of it. my engine is a 512 & the car is a 71 'cuda & the driver is a girl, not that it means much. i had the car slowed to a 10.98 a few weeks back but the weather last weekend had fat ladies singing & our stars were perfectly alined. we had PB's over most classes due to awesome conditions.
i would be recomending a victor manifold if they're anything like my bigger Super Victor.
