The hood insulation for 73-75's has the air cleaner cut out, the ones listed for 76-79's dont .(at ecklers) also they have a pulley shield in chrome, gray or black for 77-82's to keep that oil off the hood

Thanks guy's. I think I'll check into installing the full sheet without the hole. I think it would help with noise and keep my hood a little safer. It is a big block with headers so I think it might get a little warm inside.

No insulation on the '82.
