On some housings it seems they have a plug in them for a temp sender. Is it usually a 3/4" hole? Does anyone know what I am talking about?

On some cars that is where they put a vacuum switch. when engine warms up it opens (or closes) I dont know which. a vacuum line that redirects the air flow to the carb.

I just replaced the thermostat housing on my 351W ('70 model). A vacuum switch called a distributor control valve goes in that hole on my motor. It has 3 vacuum lines going to it. ------------------ JT '68 Coupe w/351W
