So I am putting a 3.73 diff in my car this weekend and I was wondering if anyone knew if my speedo is gonna be messed up. I will post a write up of the install when I am done.

no, the speedo wil be fine.
the speed gear is in the transmission, and will not be adversly affected from that...
however i am very tired and could be wrong.

the speedo ir read from a sprocket on the LSD carrier. It is unaffect by ratio changes.
