Since I put a supercharger on my car. I've got a couple of intakes and a carb just laying around. I've got one summer on the eddie rpm airgap and about 4 tanks of gas through the eddie performer intake. And I also have a quick fuel 680 ss series vaccum secondary carb I ran this last summer but I've had it about 2 years but only ran it really for a summer. I know what I paid for them new but I'm thinking of putting them on craigs list and wondering what a decent fair price to ask for them would be. I'm not sure what these go for used. I know free may come up but i am hopeing to recoop a some of the money back.lol..
