So which came first the ISX? I was working on a fleet of Macks back then so I kinda missed out. A buddy of mine swears by the ISX though. I have a N-14 in the Kenworth I am driving at the moment.
The N-14 is the electronic 855. The 855 was the "N" series that was built forever. You may remember the "Small Cam" Cummins that was rated in various horsepower versions. The "Big Cam" came out in 1977 & went through the "Big Cam I, II III & IV " before the "Big Cam 88" which was obviously built in 1988. Cummins controlled the truck engine market for many years. The ISX had reliability problems. The 855 engines were bulletproof. The N-14 is basically the same platform as the 855's. The number 14 means 14 Liter which is 855 cubic inches. I would take an N-14 over an ISX for my personal use. The problem with the older engines is meeting emission standards in some areas.
