440 A-Body swap parts needed

This site will help you with almost all the parts you're looking for. They're available new for almost everything in your list unless you're going to be more specific about what you're looking for from us.

The 727 with converter, no shipping, is going to be a challenge, however. Do you want the converter to be specific to your torque output, engine and chassis application, and intended use, or is one from a Ford, Toyota, or Chevy acceptable?
