Now that's impossible to answer without several other inputs. You need to decide if you are mini tubing or not. What look are you after(pro street or pro touring). You start pricing wheels for the offset/backspace you need and you'll understand that. So wheels and tires, what rearend is in it and what brakes are gonna be used. And if you lower the car that has an effect on how close to the quarter you can be.
All that aside I have a 8.75 housing narrowed to 46" flange to flange and I believe i can do a 10" wheel with a 4.5" backspace if it's mini tubed in a 71 dart. That is a rough measurement i did looking at doing a pro street setup.
