340 or 440
My son's 440/4sp/3.23 Dart got exactly the same fuel mileage as my wife's 340/727/3.23 GTS. Both cars are convertibles. Both cars have stock cams, as well. Handling is similar due to subframe connectors on my son's Dart. Suspension is otherwise stock big block on my son's car and stock 340 on my wife's car. The difference is felt when encountering a hill. With the 440 you just roll in a little throttle, with the 340 you've got to open it up a bit. Both are street cars.
Now to the question of whether I would go 440or 340, consider that I do have a standard bore 340 core sitting in the garage without a home...while this is the engine sitting in my '67 Barracuda convertible right now...
