Its a 1971 GT Falcon engine number stamped on a 1972 to mid 70's block with an australian late model crank. Looks like a re-stamped "bitza" to me.
Possibly a warranty block then?
Doesnt matter I missed out on it - auction ended while I was at work - didnt reach reserve and then was offered to bidders @ $300, was snapped up by another bidder 10 minutes after offer was made........
