Why was the Cummins V-555 line not so popular?
It was the worst of all of Cummins' V8s, we called them 'cripple fives' here. You name it, if failed. The V-903, VT-903 & VT-300/320/350 enjoyed a good following in Australia even though they weren't that great either. As a general rule, V8 diesels are limited by their lack of main bearings compared to straight 6 diesels. Even the mightiest Mack V8 topped out at 610HP before it reached it's limit & the Cat 3408 didn't even get that far.
