The first thing to do is to size the carb correctly! 650cfm..750cfm..850cfm...etc! From there the possibilities begin. Open up a summit catalog these days & you find that that carb market is crowded. Personally of the 3 you listed my performance preference would be #1 Demon(basically an updated holley) #2 Holley(Classic looks & performance) #3 Edelbrock("Can" take a lot of work to set up properly but can be a great running block)
