Edelbrock or Carter 600-625 cfm

I'd like to have a good, ready to run, Edelbrock or Carter carburetor. 600, 625, or maybe even 650 cfm. It's going on a 360. I have a Holley street avenger on the car now, and am tired of messing with it. Electric choke would be preferred but is not totally necessary. I'd be willing to purchase for cash, or work out some kind of a trade.
