Back in 1985 I purchased a new Dodge 1/2 ton pickup, 318 with a 4-speed overdrive trans. 3rd gear was 1:00 to 1:00, 4th was OD. Anyone have any experience putting this trans in a car? 100,000 miles later, I took the OD trans out and replaced it with a 4-speed from a smallblock 69 Barracuda that I had laying around. As I recall, the only mod I had at the time was a longer driveshaft made for the 69 4-speed.
