B series engines use a narrow rod bearing, C series and later use the wide rod bearing. The big concern is how long to go before a bearing change is needed. Most would replace them at 250,000 miles some would risk it to 500,000. It all varies on the use and care the engine received. If CAT liners are used at rebuild, one million miles are normal with proper service.
