crenwelge: I wasn't real sure about the little Jimmies I think I drove a 6V71 once but driven a bunch of 8V71 & 92s' even a couple 12V71's
It is amazing that big truck power changed very little from the 50s to the late 90s but has change by leaps and bounds from the late 90 to present. I had a 2003 four axle T800 with a 550 HP C15 and an 18 speed that pulled a four axle pup trailer it could pull down 8GPM @ 105,500 lbs. This is pretty hilly territory here in Western Washington too
