Wow so much help thanks all!!! Ok I'm not sure how to start but I will start with the temp is mechanical on the intake right beside the head. I have confirmed with a infared that I can trust the gauge up too 195-200 I never tested it at higher temps. I have not therm just a restricter plate at 1", hold on it gets much more interesting! I have the stock pump and pulleys. A new rad very big in the back of the rat with 32 feet of 2" pipe 26copper and 6' rubber. Rad in back of the pickup 142 wheelbase it's long 4'doors. I have a helper pump on the return with the fan on the top of the rad with a shroud good flow rad is on a 30% angle a little lower that the top of the intake. But I have a pressure tank that is higher and has hold 3 gal. As the hole system hold 9 gal. It all seems to work great except on those long hot fast trips. The nice this is i can stop shut it down leave fan and helper pump and cool to 140 in 5-10 min. I will add a pic as soon as I figure it out soon again I can't thx you all enough for all the advice!!
