Which site is it ? Would be interesting as our motors were numbered here although they do have the proper DZ prefix which was for the Camaro's of the time. I have'nt gone into that detail yet but at some stage hope to compare and document all our stuff. Over here everything is very vague. We are a few that speak the same language but with so many fakes around and even "diluted" original Firenza V8's it becomes a sore topic. Poeple take offence when you begin to dig and focus on specific factual details. Hence we have no option but to fit in with you guys and our small International Can Am group.
