Edelbrock Intake Issue

Ok I called the Wilson manifold place, they use Motorad thermostats, which used to be standt. This is directly from their website.

“The New MotoRad FAILSAFE thermostat was developed through years of research and development. Its unique and exclusive extra stroke allows operation in two stages. During stage 1, it will operate like any other thermostat. Stage 2 operation provides extra stroke and actually locks the thermostat open when overheating is encountered. This thermostat is constructed from stainless steel and includes an integrated Jiggle Valve to help stabilize the pressure in the engine, reduces the delay in warm-up of the engine, and eliminates trapped air in the cooling system. This is the first thermostat in use world wide that will not fail.”
