These are my questions. Why would the #3/4 rod and #3 main be hit the worst? Is the main web cracked? If there was lack of oil feed to the #3 main the #5 rod should show wear as well. #3/4 are not last in line for oil. What was the bearing clearance? Are the journals round and straight? Is the crank cracked?
Doug Those are all questions that I don't have answers for yet. I haven't lifted the crank out yet. I don't recall the clearances but they were plasti gauged when I built it and within spec. Didn't check every journal but checked a few.. I swapped bearings out back in 12' when It ate a piston. They looked like new then.. Only change is the oil pan. Ive ran the same single line Milodon plate added to the Melling HV pump. Square Pick up is about 1/2" to 3/4" off the pan floor.
