Manual trans swaps: Cheapest vs Easiest vs Best Performing vs Best Driving Experience

For ease of Engineering, the A833 is my choice. Just find all the parts or major parts and Passon Performance or Brewer's Performance have everything to finish the job. If your car had a 904, even the drive shaft will work depending on the output spline count of your transmission. I've run the standard and .73 O/D version behind a High Performance 273 and 170 on the street and loved them. Getting ready to swap an A833 for a 904 into the 67 Barracuda. Get a Hurst MOPAR A body shifter and linkage and enjoy! You just have to add a 4 speed hump, cut the floor for it, have an exhaust shop weld it in, bolt everything up, adjust the clutch and shifter linkage and go. Never tried anything else and am not ready to cut up or re-engineer any of my cars.
