Start of production thru 1425746 are Forged Rods
1425747 thru 1440712 are Powdered Rods
1440713 thru 1498318 are Forged Rods
1498319 thru final production run are all powdered
The reason for the break in serial numbers is a "test" run to be sure there were not any issues with the powdered rods. Once the process was production tested the powered rod process was used until the end of production.
There is a plug behind the oil filter in the block, just above the oil pan. Remove the plug, if you see a bolt head for a rod bolt, you have PMR. If you see a nut , you have a Forged Rod.
quite a few people pulled the inspection plug and so far the numbers checked out
