Corona the rod bearings go away from too tall gears... Lugging the engine is what puts the most strain on the rods.. I learned bout that back in 63/64.. I put 3 sets of rod bearings in a brand new 63 Ford pickup.. I was towing a mobile home with too tall of a gear.. I changed the gearing and that sucker went to town..
Although this is rarely mentioned here or elsewhere, running tall tires is the start of rod bearing failure.. changing the gear ratio will stop rod bearing wear..
