Here is what I decided to do.
I stuck with my engine for a purely economical reason. If I had known before I put a dime into it I would need this work I might have bought the rovers north short block and just built it up in my spare time but since I already had the truck in pieces I let British Car Services proceed.
Top end rebuild with all it normally includes, new crankshaft bearings, new oil seals, new fan clutch, rear ball joint assembly replaced, new power steering hoses, etc.
Once I get the truck back and get the cage back on I will post some pics. Here is one of my freshly chemically stripped basket in the meantime.
