I have a IH 140; 1971 I think.... What does the J and the R8 stand for?

Serial number: 44516 J
Motor: 351687 - R8

thanks,

The J stands for Rockford clutch. One of the suppliers to IH back then. It is considered to be slightly heavier duty than the
Auburn clutch that was also supplied. The other number is the casting number and date for the engine block. The engine serial
number is near the #1 spark plug on a flat surface and stamped in. Jim
