how large a bore with a sleeved block?

no, because it was just an inquiry. as I read it, yes it can be done but is not practical for the everyday Joe. now, if I had a Van Norman 944S, chip and chunks would be flying.

And I'd be right there with you with a truck load of blocks to see "what was what", but the sad reality is, 1) it won't work and 2) it won't work. LOL
