That was the short answer. The long answer depends on what do you want for your Dart? What do you have now? AC, rear, stock suspension? I know what I'd do. If just a nice driver, I'd change the cam, Performer intake, Holley Street Demon carb, 4 speed tunnel, A-833 O/D, decent clutch, and a Hurst shifter. If I wanted more power, that would be a little different.
