What about timing, does the timing have any affect on it? Only thing is, my truck cranks and runs great, until it gets a little to warm!!

Any ideas or suggestions, guys???
Timing will certainly have an effect on the engine temperature, this is why most people who put a hotter cam in their vehicle usually have a performance radiator and a lower temperatured thermostat. It's good to have an engine that heats up quick and runs warm, you get out of open loop and you burn the fuel more fully (hopefully without ping).

At a higher RPM you're going to notice the temperature gauge go up, mostly on older vehicles because the timing chain stretches a little and it has a small effect on timing which can possibly have a direct effect on the temperature, especially when the computer begins to do spark retarding at higher RPM's to bring up the torque a little.
