Doing some research for a friend. We have the engine out of a 67 soft window targa. the car Vin appears correct - 50xxxx, the engine type stamp is correct - 911/06 for a non-S soft window. But the engine S/N is very perplexing. It reads *911912*. The stars and font and all look very correct with no signs of molestation.
To our knowledge this is the original engine from a car that otherwise looks "normal". The number stamp is on the "back" of the casting rib as is correct for an early aluminum case but the numbers????
Anyone have any thoughts??
Thanks
