New rims/tires rubbing I NEED HELP

I don't think this is something an alignment will fix. You took a wide tire and shoved it 2" up inside the fender- True. What exactly is chamber( Cam bolt?) How much adjusmen t do I have in the t bar, Im probly gonna buy new ones anyway. How big will I need to go Iam going to be putting a 383 in here soon, I know I cant align it perfect but I need to get it close enough to drive to the align ment place
9$ blocks away) Im pretty much set that I need new rims and tires I was thinking 17x6 with 4 inches back spacing that would give me an inch inside the fender or maybe go a lot further and do like 16x4 with 2.25 inches back or16x5 3.25 or 3 inches back. I just dont wanna get a rim noone makes a tire for.
