wich is a better manifold to go with a dart or a super victor manifold.548 chevy 13:1 solid roller cam 715 lift 260 and a 269 douration.1150 dominator carb.spinning tops of 6300 rpms.

also has the dart pro1 heads 345cc

Dart ... Even better, a Wilson which they reverse engineered from the Dart ... See the Hot Rod Article on the DNE Build using a Dart modified by Wilson:

nobody knows which one is better?

Just an opinion........
Victor, Dom carb, 1" or 2" spacer. Cleanup all casting flash and make sure there are no mismatching to the head ports. (i.e......no steps)(do not open up to match the head intake ports)
Runners are likely a little smaller than a SuperVic.
The rpm your turning ain't that high so....the velocity would be slightly higher in a Victor manifold. (Although.... the difference between the two likely is not much.......?)
Mixture motion means alot!:)
That's what I'd do.

I would get a Brodix. They are a little more, but they offer more designs for specialized applications. Their fit and finish is superior to anything else I've seen. They don't seem as "mass produced" as some others.
I'd at least check them out. While more expensive, everyone that saw the one I used before I installed it was impressed, and said they wanted to try one.
