I just got my engine back from being rebuilt and was bolting my crank in to check bearing clearances and I noticed I had a Cracked Main bearing cap! Does any ine have a 235/261 Main Bearing Cap GM# 3837009 it is the third one back from the front marked w/ a "R" and has a threaded hole on the top? This sure put the breaks on my engine rebuild plans in a hurry.
