    3.06 getrag to 3.73 (installed)

    After all this time contemplating what kind of mod I wanted to do (cam or gears) for my Charger 392 superbee , I finally decided to go with the 3.73 differential getrag upgrade. Their is a break-in period I was suggested to do so can’t give any real feedback as of yet. Did some expressway driving and tested the rpms to see where I am in that department, lol. I will let you know real feedback after break-in period.

    What I have noticed is car shifts through gears pretty quick, doesn’t stay in first long and when cruising I seem to always anticipate another gear change (5 gear). None of this is a negative for me. Car revs higher and quicker and sounds better with the higher revs. Just can’t stomp it like I want , lol.

    Thanks for the report. At 60 now Im turning about 1900-2000. The RPMs you reported are totally reasonable to me. 2600 at 70 is fine!
