Mitchell in 46-48 car
If you have a Mitchell overdrive in a 46-48 car, are you using the 26.6% or the 36.6% unit? What is your differential ratio? (mine is 3:78) What do you recommend? Anyone know what the overdrive ratio of a Columbia is?
Thanks, Steve |

Re: Mitchell in 46-48 car
I have a 36% cable shift unit in my 47 with 3:78's. I live in NJ and it's pretty flat, also my flathead has a small cam, aluminum heads, and dual carbs. I'm very happy with it. I figured if I'm spending the money I wanted the biggest overdrive %. I had to notch the floor under the back seat otherwise it hit on bumps.
