Hey guys I have a 73 Challenger with 440. My radiator is a 26� four core champion aluminum radiator. I’m using clutch fan with 7 blades. I’m using a mildon high volume water pump and Mildon 180 high flow thermostat. Lower radiator hose has the thick spring in it. I’m using 1 gallon antifreeze and the rest water with water wetter. My timing is 36* total and idle set at around 900 rpms.
The car never gets above 183 when driving down the road, but as soon as I come to a stop, the temp slowly...
