What a lot of hot air about cooling. Use a 195 stat . Timing and tune up are critical to engine temp. I must be so lucky with no cooling issues on any of the hot rods/tow vehicles i have ever worked on...3 cars in particular were flogged mercilessly on road courses with no overheating or fuel delivery issues using mopar performance fan/thermostatic fan clutch, flowcooler water pumps and the proper core between the stock tanks. One car has a just a 22" radiator with a iron head 440 and it never goes over 209 on a 92 degree track day... 209 is NOT hot. [These are not stock engines]. Runs against the thermostat a lot. Every car that has been [properly] tuned by me or my tuning associate runs fantastic with a 195 sta. Using a 180 stat causes fuel to collect in the intake and burn off in the cruise mode. It called instrumentation not the seat of the pants and guessing. Our stuff pulls away your stuff...always. Go get your junk and lets go see... What no one looks at is the core temps & underhood temp esp at the base of the carb after a hard flog. I have seen cars run at 180 yet under the hood is cooking hot...It's called an infrared temp gun.
