401 Crank

 

Tremak makes a much better T-5 than the Mustang T-5 although if you go with the Mustang T-5 be sure it is the stronger version from 94 (IIRC) or later.  The earlier one is not as strong as the later one and will easily frag from the 401s torque even without hard shifts.  Even the later ones will frag if shifted too hard, particularly into 3rd.  There is a much stronger kit that can be used on the T-5 that makes it must less prone to self destructing which will obviously require a rebuild to install.

 

And who said T-10s were not as common as a Muncie?  Ford, GM, Mopar, Jeep and AMC all used them and parts are still readily available. Many, many of us have been running, flogging or racing T-10 equipped AMC for decades without any major issues and if you break something you just get a kit and rebuild it yourself or have a tranny shop rebuild it.

 

Rebuild kits are out there, but what about hard parts?  Input shaft, gears, etc?  I haven't found anyone who has new stuff.

 All internal parts are availiable for T-10's and GM Super T-10 parts can be fitted as well. If you want to go beyond a 2.64 W ratio set you'll need to have the main case modified from the 7/8" cluster shaft to 1" and the input "comboed" by Liberty gears. The combo process entails using an AMC input shaft fitted into a Super T-10 gear. The gear is lathed off the AMC piece, the S. T-10 shaft is removed, they are then pressed together and welded on both sides. I've been running a 2.64 nickle input done that way for three years while launching as high as 7500 RPM, so it does work well. Recently Dan Curtis gave an old shaft to me so I could make the 2.88 ratio conversion. I intend to see if the current tranny will hold up behind the new engine combo first.
