Time for an update and some pictures. We got the temperature under control!!
We bought a funnel that connects in place of the radiator cap and allows you to initially overfill the radiator, as the thermostat opens it allows the air to escape and the extra coolant to flow into the system. The thermostat was a 195º, we swapped it for a Mr. Gasket hi-flo 180º and set the fans to come on at 195º and turn off at 185º. This setup seems to work well and the fans actually don't run much, unless the truck is idling for a while, but the fans pull the temp down quickly. While we were at it we installed a overflow line using the same Russell Pro Classic hose and black AN fittings and hose ends we used for the transmission cooler lines as well as a black Billet Specialties radiator cap. Sunday morning we took the ZL1 and the C10 to a monthly cruise we do with some old friends, the Old Girl did great and we were lucky to have Hart_Rod join us in his Super Burb.
On the to-do list we have a rear disc brake kit and adjustable proportioning valve.
