Hi Ludo, I have a 2.25 block that needs a rebuild. It was dismantled, core plugs removed, then loosely reassembled. No head or front cover, but includes rear cover, flywheel, camshaft and sump. Standard size pistons (no rings). It probably wants a rebore.
It's taking up space in my shed so I'm happy to let it go for the price of a pint! Not sure where you are, but you'd need to collect from TD5 Scottish Borders.
Give me a shout if you're interested...
