Heat issues - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My 350 seems to be getting hot. When I am driving steady there is no problems. When I am setting at a red light with the AC on it will get up to 230 pretty quick. It normally runs around 195. Here's the kicker... when I turn the AC off the temp appears to go back to 195 in about 15 seconds... Does that seem possible?

Here's the equipment
Stock 350
165 degree thermostat (I should put a 190 in shouldn't I??)
Electric fan from a jeep grand cherokee ran off 185 degree thermostat and my in cab toggle switch..
And the AC of course...

So does anyone have any ideas or suggestions?

Thanks

Dave
