In aheavy-duty pickup truck, the best gasoline V8 may not be the most powerful of the pack. Instead, it’s the one that keeps working. Losing a few pound-feet of torque on paper doesn’t amount to much, but an engine that keeps itself out of the repair shop more than others is much more valuable. After all, for many heavy-duty truck owners, those big V8s are out on the road making money, and an engine that’s down-and-out means it’s not proving useful.
