we just put a sheid unlimited model 100 pump and a 'big charger" on a DT360 form a school bus. We retorqued head bolts to 150lbs feet and man does this thing sing! Hope to hook for first pull in next 10 days... It's in a mid 70's IH 666 with funny gears and we got it lightened up to pull in 6500lbs class, should be fun!
