416 stroker temp?

You would think if the gauge or sending unit went bad you'd get really inaccurate readings. Too lean in the carb could cause it, and yes timing as well. Have you looked at the plugs? It the idle erratic or fine?

Two small electric fans have a reputation of being inadequate. Many have solved their overheating issue by removing them and using a mechanical fan. But in your case I would look into that last.

Ya, We rejetted to holley 770 when we dynotuned the car. It has been running fine for 2 years. I was even wondering if these autometer water temp gauges are all that accurate? But non the less, the guage ran a consistant 190-195 for the past 2 years. For it now creep up to 210-215 when it is only 70 degrees here is strange. Can't imagine what would happen now on a 90 degree day. I will pull a plug or two and see what they look like. Regarding the electric fans, they have worked fine even on 90 degree days. I thought one maybe stopped working but they are both going solid. Lots of air coming through them. As far as idle is concerned, it seems the same as it always has been. Has a little lump to it due to the cam but smooths right out when I hit the throttle. I like the idea of checking those plugs. Thanks....
