PE400 Engine Number

[rohan]

I am having my poor old PE400 engine (see below) split and rebuilt at the moment and I need to confirm the engine is from a 1980 PE400T as the rest of the bike is.
The Engine number is 102872 and the frame number is 102974.
For the record are there any differences between the 1981 PE400 engine and the 80? I.e. will the crank and big end bearings be the same anyway?
