Quick Fuel Brawler vs Proform

Neither. Go find an early list Holley in what ever size you want and convert the bleeds yourself. You'll save yourself a lot of money and be way ahead.

Unless of course you want it for your youtube channel in that case get a HP or Other "mainbody" and covert an existing Holley to a wiz bang new style exotic race carb that people will want to watch so they can do it.
