This is an 18GB, 5 main bearing, short block assembly for an MGB. The bores, and pistons are standard size, as are the crankshaft journals. There are no significant wear ridges in the bores, and the crankshaft journals have virtually no scoring. All of the parts in the photos are available with the exception of the flywheel which has been sold. I would prefer to sell the lot together, but if you need one, or more parts that is fine too.
Allow me to give a brief history of this engine. I have a 1965 MGB, that needed new valve guides, and valve/seat facing. I removed the cylinder head, and discovered that it had a couple of cracks. I purchased a complete engine from a local car repair shop, and used the cylinder head on my car. What is listed here is that engine, less the cylinder head. I disassembled it so that a potential buyer can see exactly what they are actually getting. $400 takes the whole thing, or let me know what parts you need.
