This would depend on having a decent mechanic in your area that you trust.
Already thought of that.. But i am sceptical re existing block anyway. If the block/cylinders were not stuffed I would have looked at new better ones. but at present its up in the air. Anyway as far as the oil pump goes that can be sorted even with a new motor. Though I have only heard re this on the early model motors.

May be wrong but just an addition to add to issues.
