Whats the deal with 340s?

I will also offer this point of view. If your going dollar for dollar and on a lower budget, the 318 may actually beat the 340. Say a guy bought a duster with no motor. If his budget limits him to under 2k, he may go faster with a 318. Why? He can buy a good running 318 magnum for 300.00 bucks. Put a cam, EQ heads and air gap intake and should have money left over of the 2k. He will pay 1k just for a complete, non-running 340 that turns by hand. Just sayn'
