My Ford F350 (460) and Suburban (454) run much warmer when they are towing,
expecially in hilly areas. I have found that simply being more conservative on
the throttle at the end of a hill climb makes a significant different in
temperatures on moderate to steep grades. Both F350 and Subturban have factory
packages, not sure what that included, but they do have a transmission fluid

The fuel injected 460 did run hotter, but not sure of specs anymore.
My 454 engine seems to run there when towing in the hills and I was wondering
the same thing.
I am also concerned about electrical gages.
