Just bought a 67 r/t and when we decoded the fender tag it says it is a california car but what does the clean air part mean? the radiator is a 936 which said something bout clean air also. what would the radiator have to do with clean air? rad had c.a.b behind description and abbreviations showwed clean air. Just curious. thanks

In 67 California cars were locking out vacuum advance accept under certain conditions, IE under decel, when overheating... The radiator may have a bung for a temp sensor though to be honest I've never seen that on a 67... It should have the green timing control valve mounted on the right rear of the engine..

Thanks for the info! really doubt ill go to that much detail for resto but was curious what it meant. thanks again!
