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

Awesome information, guys.

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 ready to cut up or re-engineer any of my cars.

Sounds like you've been down this road before. :) Which A833 is going in the '67?

I'm starting to like this A833 route. First, I spent a good chunk of cash upgrading to an aluminum shaft two years back. I'd love to be able to keep that and not have to have it modified. I also like the idea that the car might drive more like it would have if it was hot-rodded in the 1970s. Don't get me wrong, I love the Tremec 6 speeds that I've driven but it's a distinctly more modern experience than what would fit with the rest of my build.

So I am running the stock 904 (with some internal upgrades)...which versions of the A833 would have the same spline count?

Down the road, I plan to swap in a stroker small block...so I may end up with 450-500hp. Are there versions of the A833 that wouldn't be up to the task? I gather that that the mid 1960s versions may be weaker.

How much weight does the aluminum case version save?
