Which carb to go with??

[ratty65]

I think this can go in here if not mod please move to the proper place.
I have a 1987 Crew Cab with what is supposed to be the original Quarajet carb. The choke seems to be havin problems and the trucj runs a little rich. Rather than messing with it I am thinking of replaceing the carb all together. what would be a suitable replacement? I currently have the 454bb which has been bored 40 over, a mild cam, long tube headers, edelbrock performer intake and 4.10 gears. i am not looking for more power ojust a decent replacement. Any suggestions on something that would be a direct replacement??
