If you pop the shell bearings out the size will be stamped on the back.

You used to be able to get a 'ridge remover' for removing the lip at the top of the bore. Not ideal because the clearance between the piston & bore is increased due to wear but with a new set of rings could get you by for your planned use.
I hand scraped the wear ridges in a 6-cylinder motor but checked the bore top & bottom to determine the amount of wear.

Kim is that you from instagram maggiethelandrover?

If you are not doing a rebore you need to remove the ridge other wise you could brake the top ring wten the piston comes to TDC when running.

Thank you, I appreciate the reply, I'll have a look at the shell bearings. They don't seem to have anything marked on them but do have some stamping on them. For the life of me, I cannot find a decode on these anywhere.

Are they the early small bearings only used on first series2 2 1/4 engines from 58/61 engine number starting with 151xxxxxxx could be the original ones fitted

I think you've hit the nail on the head. The engine number is 15100139, so that may answer that question. I've purchased a micrometer today and I'll have a look at tolerances. Thanks for taking the time to reply, and the headsup, I really appreciate it.
