Thermostat Housing sizes
So I am in the process of replacing my intake manifold. I noticed my M1 thermostat housing and thermostat is smaller than my replacement manifold. It’s significantly larger.
M1 hole diameter 1.5” bolt sep 2.8”
New Manifold 2.1” “ 3.25”
What gives? Is the new one set up for Fords or Chevy’s? I can’t buy new thermostat housings based on size but on application. This should be an easy thing but I don’t know what housing I need.
