Which intake should I use/ buy

With the price of gas you could use the cast iron 2 barrel intake off a 71 318...( I'm wondering when they will become valuable I have one I'm ready to turn in at the scrap yard ) :poke:I think you'll see it one day someone saying they are looking to run a BBD on a 340... if Unclke Tony sells it someone will buy ...LOL! :lol:
