The 1971 383 was the lower performance version - less HP than 1970. As far as I know it used the 23 spline A-833 and not the 18 spline version that the 440 and 426 got.

This is from a historical website:

"The major change for 1971 (actually a late-’70 running change) is a redesign of the side cover and interlock mechanism. New sheet-steel interlock levers replace the old pin-and-balls type. The setup required new internal shift forks, which were now made of cast steel instead of brass. The entire side cover setups can be interchanged either way, which is useful, since the ’70-down type is generally regarded as better for drag racing and serious abuse."

I know its not the same as the hemi 4 speed , but i was told there are alot of versions of this type trans[IE when ordering a rebuild kit] Im guessing it was potentially spline/side cover gasket and the like??? Want to order a rebuild kit and everyone is telling me they need to see the transmission first? , which makes no sense to me.
