"I have come to the conclusion
"I have come to the conclusion that the port engine, which is a replacement long block, is much better than the starboard engine, which was rebuilt. This was done by the previous owner. The starboard engine comes up to temperature in a few minutes were the port engine takes twice as long. Since these are closed loop cooled the only explanation I have is that the rebuild engine runs much hotter due to engine component tolerances. Does anyone have an opinion on this observation. The rebuilt engine runs hot under load (175 to 190) but at 160 (thermostat setting at 1500 rpm). What else would cause an engine to warm up fast?
