Simple Cooling Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm running a 2000 model vortec engine in my 63. It has A/C, power steering and a th350 trans. I just installed a Summit 2 row radiator with internal trans cooler. My question is what temp thermostat should I run? It currently has a 185 degree because I was trying to keep temps down. What temp is optimal for a vortec engine?

The LS motors like it hot, 210 and up. If you have an LS, leave the 185 in it.
