Welcome to the forum.

I used to have two IROC/Zs, both w/ TPI 350s. Are you sure yours was a 305?

Loved both of them.

 

actually i dont know if its the irocz lol i just guess cause i was told they didnt have rs in those yrs that they hadnt come back with the rs lol but i do know its a 305 haha thnks bet u miss them i would deff miss mine i love this car

 

The IROCZs had fog lites in the bumper cover and decals on the doors. Also had 16" wheels and 245-50 tires.
