ring and pinion ratio suggestion

MOST Chryslers used 3.23's in the axle. It's a decent compromise between driving it around town and having a bit of grunt taking off. I have two Studebakers with Dana 44's. One is a factory 4-Speed and that has a 3.31. The other has a GM 4L60E trans and a 3.54. That trans came out of late '90's Camaro and that car had 3.42's

My suggestion if you have a Dana 44 is to go with the 3.31's. Unless you are going to be getting on it on a regular basis, this is a good compromise. It you're going to get on it, use the 3.54's.
