Wheel Size Question.

Thanks for the reply. Im running a kit I got from CPP, nothing too fancy Im pretty sure its 73+ parts. Im not married to the width, pretty much whatever fits the best and doesn't rub. Im not sure what the 8.25 is out of I was told the 360 motor and rear end came out of an old dodge truck but its yet to be verified.

Yeah, the CPP kit is just '73+ BBP disk stuff, so that makes the front easy. With 17's and the plan to make it a daily driver what I would look at doing is going 17x8" all the way around and running 245/45/17's. They'll clear pretty easily front and rear with the proper backspace, you can rotate tires, and 245/45/17 is a very popular size so you have a wide range of tire options, anything from autoX only 100 treadwear stuff to snow tires.

In the front a 17x8" with a 5.25" backspace will work great, I recommend these wheels so much I should get a commission...

In the back I'd need a measurement from the wheel mounting surface back to the springs to recommend a backspace since you don't know where the 8.25" came from and they're available in a bunch of different widths. If you lay a ruler across the face of the drum, where the rim would sit when bolted on, and run a tape measure back to the springs that would do the trick.
