The advantage of plugging the warmup passage is, real 351C thermostats with the brass 'hat' on their base to fit the bypass port, are getting hard to find and they only come in 192 degree. With a freeze plug in there, literally any thermostat including Chevy can be used. Without the plug and with a non-351C thermostat, overheating is guaranteed since some 25% of your water will bypass the radiator through the warmup port. Some factory units in the past were mislabelled 351W thermostats. Do not run without a thermostat; overheating will probably result. Racers sometimes use sized washers to replace the thermostat, but no one I know has done the study to find the right size hole for a street 351C. As power goes up, cooling requirements also go up. Unmodified Panteras usually do just fine with a few low-cost upgrades to the cooling system. Add in 450+ horses, and the fun starts....
