R200 gear ratio?

Recommended Posts

I have a 76 280 with R200 rear end. How can I tell what my gear ratio is without disasembly? Can anyone guess at what they "typically" are? I am trying to plan out my 350 installation. I have access to a T350 tranny for cheap, but am afraid that I will be turning way too many R's. Want to be a daily driver. Any advice welcome

typical configuration was 3.545:1 for manual, and sometimes 3.9:1 for automatics, but i think that was fairly rare.

 

easier way is chock the front wheels, jack up the rear of the car, put it in neutral, mark the driveshaft, and count how many turns it makes in comparison to 1 full rotation of the rear wheels.

 

ie. if the driveshaft makes 3.5 turns to rear wheel making 1 full turn, the ratio is 3.5:1
