How Many Where Original Yenkos??

[JoeC]

Of course it is better to have THE original engine but if the car has a restored engine with correct date code and casting number and a restamped deck that looks correct, I don't think it effects the value very much. The only way to know it really has an original block is to have all the previous owners in agreement that it was never blown up or replaced. Deck restamping has improved to the point that it is difficult if not impossible to tell. Some of the old restamp jobs were poorly done and were obvious.
