(all information below is a recommendation from Race-1 not necessarily from GM)


  • Check all fluid levels
  • Cover radiator to assist the warming process
  • Start engine and maintain a low RPM level (under 1200) for 30 to 45 seconds making sure that oil pressure is over 40PSI

The low RPM period is to allow the lifters to pump up decreasing the chance of rocker arm misalignment.

  • Raise RPM to 1300 to 1500 until water temperature gauge begins to move
  • Check for any fluid leaks
  • Once the water reaches 140 raise the RPM and oscillate It between 1600 to 2000 RPM
  • Let the water raise to 215 to 220 degrees before removing the radiator shield—water should then lower to 180 to 190 or less
  • Continue running until oil temperature is a minimum of 150 degrees



 You may have to repeat covering the radiator and climbing the water temp to achieve satisfactory oil temperature



When outside air temperatures are below 70 degrees a torpedo heater or other similar device will be advantageous to your success.
