I believe that all Mopars equipped with the 440 HP engines of the '70 & '71 varieties probably had the matching 727 trans to go with it. If I remember correctly it had an 11" externally balanced converter (to match the vibration dampner on the engines with the 6 pack style rods), an additional clutch and steel in the front clutch pack with a different arrangements of springs and or less springs than a standard unit, and I think a wider kickdown band with either a 4.2 or 5.0 ratio lever. I may be mixing up some oem details with aftermarket upgrades but hopefully someone who's built some of these units can straighten up some of my recollections. Perhaps Don Verity?

So my question is what makes a Hurst transmission different form a standard unit? Thanks and Merry Christmas!
