69 340 carb aftermarket.

OK. I'll looking to buy a carb for the 69 GTS. I've heard the Edelbrock 600 with electric choke is the way to go for simplicity and "bolt on" done. The factory carb is giving me fits. Can anyone tell me which model # carb to get, and what I need to know aside from "bolt in on and go"??? Potential pit falls?
