Been struggling with the direction for the next project. A trip this weekend to Alston chassis has helped nail down a path to move forward. Planning a small block/auto in my 71 dart. Question(s), have any of you put the overdrive unit in an A body, how much cutting, and what kind of convertor? Car is getting painted right now and is minitubbed and wells stretched. Currently (325/50-15 MT street) 29" rear tire with 4.30 gears. Engine will not get built until next winter, but planning 440/340. Thanks for your help, JP.
