OK my dad has a 1966 2 door post he had a a guys start a what I believe is a 1995 LT1 and 4L60E swap. But before he finished it he passed away. So here I am trying to put the puzzle together. The motor and trans are in how can I find out for sure what engine I have so I know what wiring harness I need. I have the PVM service code of 16188051. Any help would be great. P.S. I am on a budget.
