Hi Folks newbie here!!!!
I have a '74 Charger 440 with the Rallye pkg. On my fender tag the rear axle ratios are not coded. At 60mph she's reving 4000 rpm though she doesn't give the impression that she's reving too hard. I am concerned about driving highway speed with her if the tach is accurate but I don't know how to check it or how to find out what the rear end gears are.

I was hoping someone may know what came with the "Rallye package" for axle gears in the '74's


Thanks
