There have been several threads on this subject lately. I believe the best out-of-the-box street carbs today are the new Street Demons. If the car will see more street duty, the 625 would be the better choice.
Master, again and still

I agree that a 750 would be the largest carb for it. The 383's I've messed with did not like big carbs like a 440 does. I had a mild 383 w/ big valve 906s, 9.5:1 compression, MP 484/284 cam...it ran WAYYY better w/ a 750 than it did when I tried my 830 holley DP on it.

The 800 is a bit large for the engine. 750 would be my max size for it.
You did get the tuning kit for the carb right?
You also did not give a wholeot of info on the engine. What exact cam?
Headers?
Etc...
Depending on what your trying to do& have in the engine and the cars set up, converter, rear gear, tire size, etc.... You may even be able to use a smaller 650!
The cam 475/494 Voodoo with Hp manifolds,DP4B intake, 323 gears with a 2800 stall. Motor is 30 over with block decked and the heads shaved on it. Has KB pistons and is suppose to be about 9.3-1 on compression. It is an auto. I did get the tuning kit but I think I will be better off getting another carb. I don't remember the back tires they are big 15" ones that would fit the car. I just have never had good luck out of the edlebrocks. Ronnie

, but they do work great out of the box 
I've used several of them on bigger C.I. drag race motors and smaller pump gas street motors like yours
