From my research both of these V8's (6.0 & 5.6) are 3000 to 5000 hr motors and I would hop in either one and drive them to Cali and back without a worry.
Yeah, when you look at auto engines in terms of
engine hours, it's surprising yet very do-able in cars and
trucks unlike airplanes that take off at 105% power and cruise at 70% throttle most of the
time!
Imagine a 300Hp V6 car using 250Hp nearly all the time - you'd never make it to 5,000 hrs!
The average car only uses 25Hp at a steady hiway cruise on flat ground! That's why flying cars, if they ever come
won't be getting 30MPGs, they'd have the throttle way up to stay aloft! LOL
Fun fact: I got into the OBDII data on the daily driver and saw my fuel trims are running 11% low, ie, lightfooting
it! I wonder if you can judge if a used car is driven hard if fuel trims are say, + 15%?
