I went to tech archives for the axle ratio calculator, but it kept taking me to 1/4 mile calculator. Anyway the pinion gear has 14 teeth and the ring gear has 41 teeth. The way I used to to do it and I might be doing it wrong, I come up with 2.98? 2004 Dodge Rumble Bee 5.7 Hemi 1969 Plymouth Roadrunner
