3.03 to 3.73
I'm thinking about changing to a 3.73 rear diff but have a question for those that have this diff.

What are your RPMs like at around 80mph?

Depends. Use one of the gear calculators. The Richmond gear website has one listed under Street Performance.

Measure your actual tire height, punch in the ratio for your tranny and it will show you what you are dealing with.
