Max Underhood Temp?

Anybody got any idea what the maximum underhood temp should be for a 7.3 PSD?

After freezing my 'nads off in the Ice Age of '14, I'm thinking about a grille block. Not only for cold weather (I ditched my EBPV because it shut open and was like a jakebrake all the time) but also for warmer weather MPG.

These trucks are designed for heavy load operations in Death Valley, but that place isn't on my itinerary in the near future and I don't haul as much as I used to. Grille blocks are supposedly good for 2-4% improvement and for me that's big.

I use a winterfront with the windows closed up to 50 degrees then open 1 of the 2 windows. It helps warm up and seems like a bit more mpg (never bothered to calculate if theres a difference or not). In the summer I swap grills so I have my winter grill and summer grill (without winter front). I never froze in the winter before installing the front last month though.
