MCI8 with series 50 and Allison 755

What serial number they did using the upgraded balance shafts in the 50 series ? I remember they had a low oil pressure at idle something like 15 lbs when they switched and you had to buy a kit to resolve the problem.I know the balance shafts and oil pump can be expensive on a 50 series from DD

All of the one's that I have seen run over 40 lbs at idle.  The shaft in my bus has been replaced at some time.  I can see where it hit the oil pan.
