Manifold is a Holley Street Dominator…ran really well with the 800 DP I used to have. I also have a new Victor that I’ve never ran…but I bought it to run with Fuel injection that I never ended up finishing.
i was just wondering if the manifold would complement the ported heads or hinder them. if the heads are 300+cfm and the manifold is 280-290cfm would spending a bunch of money on a carb make a noticeable difference? just asking. would the victor manifold, which can make more power, and a better carb add growth plus performance? i think maybe i'd try the victor first and spend money on a carb second.

as far as losing some performance goes a lot of factors play in. driver, weather, track, old tires, fuel delivery degradation, maybe a combo of all? i think i'd try to look at a broader picture.


We run ported 300-ish cfm heads and also run a Holley Street Dominator. Streetwize (Bobby) here on the board ported this SD and compared to an as-cast, it picked up a tenth on the dragstrip. Translated to about 12 hp as I recall. We also run an 850 Demon for a carb. For a heavy street car it runs pretty well and has great drivability.
