Harmonic Damper "PRW" help!

[b5blue]

  So I bought a new PRW dampener (#2344041) for my external balanced 1973 440. It comes with 2 adapters and instructions. There are no part numbers on the adapters so I called "PRW" to find out which one to use. The guy had to call me back and when he did he said: "use the middle one". I explained there is NO middle one?
  He settled on using the biggest one as you have none/small and large and I'm lost. The thing I'm NOT doing is gambling. Anyone know for certain the correct weight adapter (Large or small.)

There were only two 440 external weight configurations; the '70-'72 440-6 and the '70-'71 440-4 with forged cranks used less external weight than the '73-later with a cast crank, so your engine needs the larger weight.

Thanks John! I found a damper pic on 440 Source and they sell the 6BBL weight separate. The adapter, key way and timing marks match with their damper also proving you correct.    https://store.440source.com/Internal-_-External-Balance-Black-Damper/productinfo/200%2D1128/

I'm kind late to the show. Many 1973 440s were forged cranks and internally balanced. Are you sure yours is externally balanced?

This is the engine, E on top pad and fat dampener on the front:  http://www.dodgecharger.com/forum/index.php/topic,77951.msg875594.html#msg875594  Thanks for checking in, I appreciate it. (It is attached to a flywheel/bell housing.)
