Which Carb for the Spring

DartSport - I currently run an Eddy 600 1405 on a stock 340, auto, 3.21 gear. It was pretty much bolt on and go. A very streetable and reliable carb. I just happen to be looking for a little more and will be upgrading to a Holley 670 Street Avenger. It's already on the way. I'll let you know how the tuning part of it goes.
