Ive listened to some of the drivel he is spued before about different vehicles and I cant beleieve he is a real mechanic! I think the best course of action is buying the vehicles he deadpans and staying away from the ones he recommends..
What about a shaker hood scoop mechanism from a Pontiac Trans am? They make repro kits to make the phony shakers scoops into real ones. that way you can open it when you want and seal it off when you need it.
I remember Eaton did have one like this and there used to be an Ected by Auburn which has now been upgraded. But I think this one had clutches for LS and some type of electronic locking ball ramp set up.
