The caps are indeed numbered and in the correct position.
In the past, i built 4 to 5 stroker blocks and they all turned freely with the caps torqued to spec. I know measuring the used bearings is not ideal but despite the bigger clearance, 4 out of 5 caps prevent the crank to turn freely. Tonight I will measure all the other diameters. Let see if that gives more insight. This engine ran only 20 miles after the last rebuild according to the previous builder and seller. The original advert and pictures are on this forum, showing a nice and shining engine. I have a micrometer and guage to measure the diameters. I have heard the engine running on my visit.
I remember the huge wobbling of both waterpump and crankshaft. Also the rear pivot bearing to support the gearbox shaft shows ovality.
The harmonic damper was bad for sure since i noticed the outer ring was not in line anymore with the inner portion.
Perhaps better to buy first the new bearings and restart the measurements.
The rear seal is split rubber seal which is greased and is not the route cause. Number 5 cap is the only cap which let the crank turn freely.
