    If I remove the t-stat will it tell me what degree it is? 160, 180

      Maybe - though not all thermostats are marked accordingly. The OEM (original equipment) thermostats in the 1980 5.7L engine have the following temperature ratings in degrees fahrenheit; 160, 180, 195, 205 - so yours would be one of those.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Contact the local dealerships for a copy or information specific to a particular service bulletin.

      I actually work at a Chevrolet dealership. The camshaft actuator solenoids are causing your light issue. Never once have I done the connectors.
      Your noise on cold start up is from your timing chains. Your vehicle might be under power train warranty. They need to replace chains, tensioners and actuators. There are new designed chains for this motor.
