I remember when the Chevrolet "348" was considered a Big Block and yet the enthusiasts stuck with the "283". The 6.0, a descendent of the "283" suffers from its mediocrity. Neither the best nor the worst for most applications, it does a pretty good job for mamy of us. No high tech turbos, overhead cams, or expensive diesel technology to brag about, or break down either. It seems to work well for those of us that choose to keep our trailer weights under 8,000 pounds or so.
The only thing a newer 6.0L and the 283 have in common is the 4.4" bore center. Mediocrity would be a relative term in this case. It seems the OP has a better than mediocre engine for his needs.
