I hate edelbrock carbs personally. They never have given me good performance on my cleveland (been through 2). I had a holley 3310 600cfm for a while. It did alright, but off the line power is much better now with my holley 770 street avenger. The street avenger was designed from scratch to be a great performing street carb that provided good fuel economy/part throttle acceleration. Speaking from experience, I'd put a 670 street avenger on for your purposes.
