Now if you put a set of twins in one with a valet switch you can make as much power as you want and still keep it streetable. Economy is all in how you drive it. I get a consistent 17.5 out of my 97 around town commuting, and 20-22mpg on the highway depending on where I'm going and what the weather is like, my lighter 99 24v barely get there empty, without a toolbox or a ranchhand bumper.
Simply put, the 12v is the most reliable engine once the KDP has been tabbed, no question about it. After that things get murky. IMO, it would go in an order like this:
1. 12V P-Pump, Any year (But the 98 is the nicest)
2. 5.9L CR (Again, year doesn't matter much, but 04.5's seem to do well)
3. 6.7L CR (All years so far seem to be doing well)
4. VE 12V, Preferably an Intercooled model, but reliablility wise they're all similar
5. VP-44 24V, Between 53 blocks, lift pumps, and Injection Pumps, they're asking for trouble, but those can be fixed with enough cash.

a non intercooled VE truck is more reliable than a intercooled VE truck cause the intercooled truck has an ECM........
