I just bought what I am told is a T-Bird motor and transmission (302) and am trying to distinguish what year it is. I have not been able to locate any numbers on the block. All I found was a big "Z" on one side and a "29" on the other. None of which does me any good. Any help would be great! The valve covers were manufactured in 1988 so I am assuming 88 or 89, but I have also been told 91-93??


Thanks.
