I have a problem in my 302 that I cannot quite put my finger on.I had a leaking stat gasket on the goosneck so I pulled the stat and gasket and replaced both while I had it apart. My motor temperature is hunting from 180 to 210, and I thought I may have a bad stat. It would heat up slowly and then rapidly fall off as the stat opened up. You could actually feel the heat buildup and release when the stat opened. So I purchased a new stat and gasket and installed it correctly with the sensor toward the block and just idled the engine to warmup temps. PS it has no weep hole tp put in the 12:00 position.

It appeared to do the same thing, now I have not taken it out yet and driven it and also let me state that the fan is on all of the time on this engine and I have not installed a fan controller, but do not know if it would help or hurt.

Whew, any suggestions?
Thx Kirk
