I have decoded the engine, it is a 1975 Firebird engine with 185 HP.

I gave the owner an offer of 2500 USD and he did reclain and relisted it on Ebay again with the numbers he did find on the engine and as a non matching numbers car, he also told me that the reserve was over my 2500 USD offer.
He did also use the old pictures and did not mention the broken windshield.

Anyways so are project rustbucket over for my part I am just happy that I did find out that it was not matching numbers before I made the payment ( Thanks Bjorn !! with out your photo's I would have been stuck with it), maybe I will return with a new project in the future, who knows....
