If you haven't lost any power, or the engine isn't missing I would doubt that you bent a connecting rod. I guess it could be a wrist pin bushing, but I have never seen one fail, or be out of spec unless there is a pile of miles on the engine. I have mic'd pin bushings on engines with 300,000 on them and they were within spec. As for having PMRs, you have to go by serial number of the engine rather than the year of the truck. It is a more accurate way of telling what you have. Also, I have seen engines that were serialed as having forged rods that had PMRs, and vice versa. The best way to tell is to pull the inspection plug in the block and look in the crankcase. If you see a nut holding the rod cap on then it's forged, if you see the head of a bolt then its PMRs. If I were a betting man, I would bet that you spun a rod bearing, but that is just a guess. If you have, DO NOT reuse that rod, it will never hold a bearing correctly again, no matter how you have it machined.
