IM RICKY BOBBY

i have a 750 cfm edlebrock carb with about 500 miles on it with electric choke and i was hopping to find someone who has a demon 600 or 650 cfm or so and would want to trade..... where would be the best place to look?? i thought about ebay but then i thought it was more for selling items not for trading or am i wrong about that....??? thanks for the help
