Double Engine numbers??

That is a factory restamp. I have been looking for a good picture of it!

Ford renumbered thousands of engines like this at the Rouge for various reasons, mostly including engines that were returned from dealer or from assembly, with some problem.

Rather than scrap the engine completely, many were torn down and 'repaired' at the Rouge, and then newly renumbered after passing final test for the second time.

This is all fairly well detailed and substantiated in the Engine Production daily logs in the archives, and in fact there is the exact old number/new number records as well.

On my next trip to the archives I could find the exact record of the renumbering of your specific engine.

I have known about this for several years, but that is the first good photo I have seen.

Shouldn,t the restamped number be higher than the original number? I assume the original number is the higher number which has a line stamped through it?

This is probably a dealer re-stamp. Most of the blocks I have that show obvious factory stampings are stamped close to or just under the deck and are very straight and uniform. These show the top number as being just that as if they were stamped using a holder for the stamps. The lower number is more out of line and erratic in their relation to each other. I don't believe this is a factory re-number tho, it probably did happen as Vince said, just not in this instance.
 
Also, it is possible that it was renumbered by a dealer, and not the Rouge.
For example if a bad engine was replaced with a compete factory 'crate' engine.

Were engines that were sent to dealers as service replacement engines numbered in sequence with the ones going into vehicles.
I would have thought they would not have been numbered but have nothing to indicate that.
