Wow...it seems strange to me also that it's only running 40 mph with 3.73s.
But the speedo read 40 and my girlfriends speedo (driving behind me) said 40. And this isn't my first time building a car or driving something I shift by "ear", and at 40 it was running pretty hard. I will wire a tach up and see what RPMs I'm running.
I replaced the enclosed driveshaft 4.11 rear to avoid this situation.
Thanks for the help. I'll let y'all know how it goes.
