Re: 3 speed questions
Can you post a pic?
The original three speed would have been a Saginaw (with one of two low gear ratios) and was essentially a passenger car transmission. K

Re: 3 speed questions
Do you do any highway driving with your truck? I have a lot of experience with 250 straight sixes, and may have some advice you can use.
