Welcome to FABO from Southern California! You're going to have fun here. Lots of great people with a boatload of information for most any question you may have.
Nice looking Scamp! FYI, the person you bought it from must not know much about 340s because they never built a two-barrel version - all 340s had four-barrel carburetors except for the six-pack setups on the AAR 'Cudas and Challenger T/As.
