Hey ASU, whats up? Im right down the hill from ya. Well Pgh. Maybe we'll cross paths soon. On the heat, sounds fine to me, but beers are flowing easily. chug. Dont be afraid of operating temps. Everyone wants 180, but 220 if fine. My 51 Chevy with a 62 261, 235 head, mechanical fan, 180 thermostat, runs in the middle of the gauge, whatever that is, lol. But i notice when its toasty out, and the heater core flow is shut down, it runs atad hotter. So what. It working as designed and i can see da slight change with the core open or closed. What im saying is that everything you do changes something. Play with it and find out what your comfortable with seeing on a gauge. If you move the sender away from the hottest spot on the engine and like it better, so be it. That don't mean its running cooler, your just seeing a reading from a cooler area. If it was overheating, youll know it , regardless of the gauge. Running, starting, power, etc issues. Id put the sender where ever it seems fit, then leave it there. Electric fans are preference to some, but like previous stated, have there place. I like mechanical myself. Drive the crap out of it. Hot, cold, hiway, city, long, short, whatever. Youll get a feel for it. Then only then change something like, thermostat, fan, rad, whatever. Then drive it all over again. At that point. Youll know if you are helping or hindering the cooling aspect of your vehicle. Keep us posted.
