I recently installed a 5.0 roller motor from an 86' SCCA car in my 67 notchback. The problem is in the cooling system. I have a 2 row radiator and stock fan and shroud from a fox body. The radiator cap and thermostat are brand new and she's got a jeg's overflow tank.
When the car is started, the temp gague will creep up slowly, like over 15 min to overheating. The strange thing is that the heater in the car will be ice cold. Then, if the pressure (steam) is released, the car will run in the middle temperature range and the heater will blow moderately warm heat.
Do I have an air pocket in my engine or should I be thinking about a head gasket replacement? I've checked the plugs and they all look to be ok. And I know the next step is to compression check, and that's going to happen asap.
Any thoughts??? Thanks for your help
