My uncle has a 1982 CJ7 and just completed a 4.3 TBI & 700R4 conversion. It's pretty sweet. He said that on his 4.2 he had some type of valve that kept the coolant from running through the heater core until the motor was up to temp. I looked at my 83 CJ7 and I have nothing like that. All my heater hoses go directly from the intake and pump through the fire wall. Have any of you seen anything like this?
