Help Identify this engine!!

Al, the various sumps are interchangeable on the different engines, but not in a carrier A std. U.C. carrier should have the 11 inch clutch plate and the associated bus (heavy springs) 11 inch pressure plate, but because the two piece sump does not fit in the carrier (read Andrews post) you have to fit the clutch before the sump is fitted. There is also a one piece sump with a big removeable plate on the bottom. They dont fit either (I'm not 100% sure about this? Can someone confirm?) You need a std car sump for most carriers.

Thanks for that. I felt a bit foolish asking the question as I should have looked at the F60S but that is an hour away and I cannot get away at present.
The reason I asked was because we have a 3.6L engine in the F60S and want to fit the correct 3.9L one. Having just bought one in what so far looks reasonable condition (standard bores and only 7thou wear anyway) I was trying to date what I have. Stamped on the front of the block, on the mating face for the inlet manifold, is "11 54 220". I very much doubt it is the 220th engine built in November 1954 however.

Kind regards,
Alastair
