Gear Ratio help???

[mj73rallye]

Hoping to get some help with gear ratios....

I have a 73 Challenger Rallye. It is 340 4spd and I am trying to determine the gear ratio. From what I have seen there is a ton of options....curious if my package led to a "std" ratio or alike? I still have fender tag in tact but the codes I was able to pull up none of them allude to axle ratio....Any thoughts other than pulling cover etc?

Put in on jacks and spin the tires, count the driveshaft revolutions, simple calculation.

Yes...See Above....Its probably 3:23

Crawl under and see if the little metal tag is still attached to a third member bolt. Mine was on my '72, and it was a 2.76

Last summer I swapped to a 3.55 sure grip from Dr. Diff and now I'm half thinking I want to go back to 3.23 or 2.76 or something in between, since the new motor will have more than enough torque to do what I want, and I like driving on the freeway. Never ending projects...
