What Carb to Run on my 408 Stroker Duster.

At the moment I have a Holley 850 QFT race carb on my 408 Stroker engine. I bought my 74 Duster back with the Original 360. Buddy of mine had swapped in this Stroker setup with Eagle kit. Would like to make a bit more streetable and tone the carb down. Any suggestions on that? Thanks.
Is there something wrong with running what you have? I believe my 408, which has an 850 DP Holley, would like a bit more (950?). I'm just too cheap to go buy one!
