I am just putting my restored '71 on the road. The engine shows about 190 degrees or so on the digital gauge. I'm sure there is a 185 degree thermostat in there. This is a high compression 400. I am considering installing a set of electric pusher fans in front of the a/c condenser to help cool the engine and also cool the freon and reduce the high pressure side. Anyone have any experience doing this? Should I put a 160 degree thermostat in it? When working on the a/c system this morning, the high pressure side was over 275, but would drop some when a fan was pushed into the grill.
