I want to switch from 14" rims to 17" rims on my 1971 challenger. What width rims do I need and what back spacing. I want to fit the largest tire I can without rubbing. The car is stock specs. I am going with larger brakes and need the room. Also I will be rebuilding the front and rear suspension while I'm under the car. I am thinking I need 17x8 with 4.5 backspacing. What size tires too.

Also on another subject: Anybody put a fuel injected GEN 3 Hemi in their muscle car? How hard was it? What did you do fo wiring? Did you use fuel injection? This is my next project.

Thanks
Sanman
