Hi, I am being offered a S2 incomplete E Type engine, the engine number appears at odds with data on the XKE Data site and also the XKS. com site. The number on the block is 7R 9340-9. The 7R appears correct for a S2 2+2 however the highest number I can find is 7R 40252-9. The block appears visually correct but the number concerns me as being so far out of the number sequence.
Has anyone come across such a number or any explanation for the discrepancy? TIA
