New guy on the forum here. I have a 70 chevelle 454 ss. I can’t seem to get the flapper to open and close when driving. Opens when car is off. Closes when car turns on. No kinks anywhere. Doesn’t work with hood opened or closed. Tried it with check valve on and off and in both directions. Hooked...
I got my 70 Chevelle in 2010.
A few weeks later I got my build sheet copy from George record keeper for GM Canada. Thanks Canucks !!!
The previous owner went with the non functional Cowl hood. Already had close to $100k in the car.
So it had it, so I want it.
I'd love to retro fit my hood...
I understand from reading on different forums there are two styles of gm cowl induction hood. How does one distingush between the two and the same applies to the differences between those two and a reproduction hood. Your comments are appreciated - thank you!
