At any rate, the C6ME is the key to UK registration.

It's common knowledge that the standard Ford methed to identify parts IS like the code you have on your motor.

My connecting rods, for instance, are C6AE-E. C6 (1966) is the year, end of story. The AE-E indicates a SCJ rod (in this case).

My block is more complex, it has NO NUMBERS at all. But through knowledge of the side oilers, etc there is no doubt it's a 1968 service block drilled for hydraulic lifters side oiler. How I would "prove" that in the UK would be a nightmare!

My heads are C4XX-X,,, (1964).
