Not sure on the PCM's, I believe they would be the same but in my Holman Moody the water goes thru the block first then out thru the thermostat then dumped into the exhaust. The thermostat sits in the hot water block side. Once the engine reaches operating temp the thermostat never touches cooler water. All conversions being different,mine runs on a good day,no higher than 20 degrees below the thermostat rating. Most likely the reason that later HM's added a circulation pump.

Mine is a Commander. It is a lot like a PCM. I believe the little block lets water flow through the intake and out of the exhaust before the engine gets warm. I would think that there are a lot of people on this site with more knowledge about this subject me. Hopefully one of the will explain the block better than I can.
