[Tigers] All I have to do is learn how to type. "5s" & "6s" do look kind of alike.

[James Lindner]

Hi All

Not trying to hijack this thread but I thought that while everybody is looking at their casting and build dates I would throw out that I am looking for a C40E block with a casting date from oct or Sep 63.

My Tiger is one of the first to roll off the Jensen line (0033) on 19June 64 with an engine from the E7KL engine group. When they found the car the original engine had been replaced by a 289. The P.O. who restored it put in a period correct 260 but the build date had been decked and it has a casting date from Apr 63...probably a bit early for an engine in the E7KL group.

Anyway, if anybody has an engine with the casting dates above and you are considering selling it...let me know.

Thanks

Jim

He said the last “C” in the date code is actually the shift that it was manufactured (machined) during.  1st shift is A, 2nd is B, and 3rd is C.   So my guess is that the block was cast a couple of weeks before machining, then on the early morning if the 31st of March it was machined and made ready for assembly.  He said the probability of fonding a matching date code down to the shift was pretty slim.
