Hopefully somebody here will be able to help and advise. I have a 5L HO Mustang engine apparently from an 87 mustang. i want to use the engine in a replica GT40 but for UK registration purposes i need to prove the age of the Engine block.

Now i have found out all about the 4 digit ford casting number scheme but nothing is cast on the block that correspond to this. All the other bits in hte engine, Crank, heads, etc have E7xx cast making it 87, but he vehicle inspectrate only cares about he engine block.

So i have found various casting marks but nothing suggesting what should be there.

Can anybody help?
