GM 3877660... While working on the Elky I finally remembered to record the numbers off the thermostat housing.Does anyone know what this fits? Or is this a generic Chevy part or a part for a specific application?
I'm just wondering what this is.
Also,under the part # is a triangle with A 2 after it.

TTT
Does this number belong to a 69 big block?

I do not have the Corvette or Truck applications
