You can probably switch that thermostat housing out with the "right one" you cant really see mine.

Hmmm. I am not a mid 70's guy, but isn't that the job of the thermostat? They had thermostats in the mid 70's, didn't they? This has me really curious, so you guys please continue to post as to why there is a vacuum hooked into the thermostat housing.

I think the piece you see on the water neck is a vacum switch that opened or closed when the water temp comes up

I didnt mean it controlled the coolant. In my last 70s car (a z28) it had vacuum switches that opened and let vacuum pass through when the engine warmed up. It controlled things like spark timing for the emmisions controls

Ok John, I am not up to par with mid 70's motors. I am just very curious as to why there are vacuum hoses connected to the themostat housing. Why?
