I got the motor running last night after modifying the drive shaft. This engine has been "freshened up" and I don't know how long it has before it needs a rebuild. I'll replace the cam gear and shaft then.
FWIW, the motor was in a car I bought a few years ago from the US. The work was done over there and it has 0.006" wear in the bores, though they are parrallel and the pistons have been stretched to take up the slap. New rings and a valve grind, and it runs OK for now. Bearings were quite OK. The clearances were adjusted by removing shims - about 0.005" on each main bearing. Its future is to run as long as it continues to do so, then a rebuild with counterweights, new cam and a couple of other things (including a cam gear!).
