Not Ranked
I have always liked multi carb setups, as I put dual quads with 600's on my 460. Vacuume secondaries are the way to go on the street, as Dan said they open only as much as the engine demands.
The 390 cfm will give the best throttle response but will suffer at high rpms, the 450's are mechanicals I believe ??? and if so I would use as my last choice. The 600's will not have the throttle respose of the 390's but will make up for it in the 3000+ rpms.
