I got my wifes Capri running last week, it runs awesome, we kept the mods to a minimum, better than stock cam, and a .040 overbore. IT overheats though, I put in a 160 degree thermostat(fail-safe), a new water pump, radiator cap, rodded out the radiator, new flex fan and shroud, it has an overflow tank, and I even put in some super coolant which was supposed to reduce the temp by up to 20 degrees. I have an aftermarket mechanical gauge. Cruising around is fine, but the moment the car stops, the needle starts climbing. It got to 240 the other day by the time I managed to find a place to park and let it cool off. The radiator is a 2 row, which is what originally came with the 302(this car was a 4-to-8 cylinder conversion.) I have the timing set correctly, what else could cause it to overheat so badly?
