What carb. should I buy?

I have a 67 Dart pro street car that I run at Test/Tune opportunities. Otherwise it is street driven around the area. Engine is 383 bored and stroked to 496. Forged pistons, Trick Flow 240 heads, Edelbrock Performer RPM intake, .564/295 Comp Cam. Currently I have a Holley 850 double pumper.
What brand, size, model carb would you guys recommend for this combo?

Car has 4.10 rear now. 4.56 is in hand and going in this winter.
Tires are 31 tall.
If you want max performance on your street car, then a 1050Dominator with skirted boosters would be your friend. I have a street 511 with 1150 Dom. Very streetable and as good of street manners as a 600 holley. Contact Dom@Thumpercarbs. He will hook you up with a carb tested on his Dart before he sends it.
