Hi, a couple questions here, prior to removing my old engine (gen1, 350) the temp sender and guage worked. Put new engine in (gen2, 383), and guage cluster was rebuilt and now not getting temp reading. Thought thermostat wasnt opening but all the hoses are hot and I'm getting heat in the car when running the heater. The car was definitely run long enough that it should be showing something. New temp sender as well. Same wire which looks old. But again it worked fine before. The thermostat is new, plus when the car is off and I squeeze the upper hose I can hear the coolant sloshing around and hitting the cap. Hose doesnt get firm while running though. Any thoughts why I might not be getting a temp or at least not a very high one? I'll shut the car off and turn the key back on for accessories and the temp will creep up to like 110 - 120. Second question is the motor makes a very dull hum sound that comes and goes as it's running. Do the rings make some noise while the engine breaks in and rings seat?
