Edelbrock 1400 600cfm Carb

So I confess that I don't know enough about Carbs to know exactly what you are talking about. So this is an economy carb and not for performance. But it can be changed over? I have a mildly built 318 and want to go to a better carb. The one on it needs rebuilt plus it is so old it looks like crap. I would like pictures of this one because I am interested if it a good one for my little shortbed 318 4sp truck. 1984 vintage. I am definitely interested but don't want to buy something that ends up on the shelf.

Same basic carb it just has a nipple to hook your charcoal canister to and the 2nd vacuum port to use an EGR with if you would like. It's a 600cfm Eddy carb just like the so called "performance" version. The difference is minimal and they have the same performance capabilities.
