25% underdrive pulley
When I did my cam,valve springs and headers I installed a 25% underdrive crank pulley.My car is running about 20° warmer now at highway speed and idle.Are any of you guys seeing the same thing?

When the cam was installed was tuning done? Maybe your fan setting needs to be lowered. Your idle and part throttle mixture might be a little lean too with the cam creating more heat. Your water pump should be pumping enough water even with the UD pulley and certainly enough if you have your idle slightly higher with the bigger cam. I don't think it's the pulley.

yea its normal with the U/D pulley. It slows down the waterpump so thats why the car is running hotter.
