318 intake question
i have a 1977 318 motor i am putting in a 1973 challenger. on the intake about an inch away from the thermostat (on the left side when facing the motor) is a threaded hole about three eighths of an inch around. what goes in there? im pretty sure its a temp sensor, but nobody can find the correct one. when we look it up at the parts store it says"part does not apply to this vehicle. i found a sensor that i thought was for it but when it came in the threads were way to small.does anyone know the right part number for this sensor

Just hit the 'new posts' or do a search. I haven't got this thing down pat either. Probably better ways.
About the hole in intake I was thinking of that temp sensitive vacuum deal that they used during the smog years. Had about three ports to hook up vacuum lines[?].[I guess it worked like a vacuum switch] The only other guess is that there was a thread adaptor in there to reduce the hole down to 1/4 inch. Only things I can think of right now. Smog year motors were kinda crazy with the plumbing and electrical and vacuum lines. worse comes to worse you could plug it or use adaptor or maybe if you got a good parts guy, he can find one that works. I'm thinking temp. senders are application specific to the dash; actual gauge or idiot light equipped.{?} Mopar tended to use mostly gauges for the temp reading. GM liked to use the idiot lights.
