After 17 years I finally got 3.73's in with my Yank ~3200 stall, and new rubber. Computer reprogrammed and just want to report in the SOTP difference was HUGE!

Better late than never !

SFC's and Brake upgrade are next...

 

What was the rears' ratio prior to the 3.73s' ?

 

3.23's, wasn't expecting a whole lot being only a moderate step up, but was pleasantly surprised!

 

3.23s' to 3.73s' is a 15% increase in torque to the pavement.

Along with a stall change



be a perceived 'feel like' 150hp SOTP gain.
