If anyone can help me i would appreciate it. I have a 1977 Z28 i just bought. I towed it back from near niagra falls ny. The car has a 454 chevy big block enjine and has wider tires on back p265 also the transmission is 400 sport shifter. I changed the front springs and put heavy duty springs because car was sitting lower in front because of heavier engine. i also changed front shocks and replaced sway bar links brakes front and back and resurfaced rotors upper and lower ball joints in front replaced front calipers and front alignment. My problem is i put new tires all around and the front passenger side tire is wearing out in 500 miles the outer tread is chipping away badly and the drivers side is also but slowly compared to drivers side. Does anyone know what can be wrong?

Take it back to the place that aligned it. Unless something broke since it was aligned they did something wrong. When you do a front end alignment you are suppost to check all the items that could cause the alignment to shift and wear our the tires before you adjust anything. When the alignment is done it should be better then 1/32" within factory specs. To damage a tire in 500 miles something is way out of alignment. Most likely they forgot to tighen the tie rods.

There are some issues that are common with second gens that your 454 would make worse but those issues would be reasons why your car could not be aligned. If it was aligned those are not the problems.
