My roadrunner doesn't have the air grabber hood, so its not fresh air for sure. I found this other thread that gets into great detail about this same topic. Found it last night after spending hours searching:

To some, the 4667 is the bigfoot of chrysler carbs. So I'm guessing a 4667 and a 6191 holley would both be correct?

I saw a pic of an original holley in the thread I posted and I had to laugh. In one of the boxes the previous owner gave me, it has the complete idle solenoid and wires from the original holley the car came with....but no carb of course. From what I read the idle solenoid is used only on 3 or 4 speed cars.
