Re: 70 Chevelle Cowl Induction Hood
LACK of vacuum is what makes them open. When the car is off the flapper is open, with it on itís closed. Itís working, just not as quickly as you want.
I find it incredibly hard to believe your wife floored the car and it the primaries did nothing. Iím almost certain you are not looking at the correct part(s). That being said, even running crappy will have extremely little effect on the flapper. Higher RPMís has nothing to do with it either, LOAD does. At a standstill (as you said) there is NO load. Replace the pod and remove the stupid slow control valve and be happy.
