One big factor to consider is running without an air cleaner. Here in Arizona where the ground is always dry and dirt and sand are the norm, not using a filter is a tough way to go. The single 4bbl with an air filter will perform much better at any rpm than the Webers with air filters. I have both induction systems and have used both on my Kieth Craft built 482ci FE. The car has a better hit at any rpm with the Webers(4x48 IDA's) than the 750cfm vacuum secondary Holly. When I put ANY kind of filter on the Webers however (and I've tried several) the performance suffers drastically. The Holly runs great with or without an air filter. My car is much more drivable and smoother with the 4bbl. Overall I prefer the superior drivability with the slight performance penalty of the 4bbl with an air cleaner to the open Webers. At the Pavillions on a Saturday night with the hood open however, people go nuts over the Webers. Do you want to drive or do you want to show??
