I read a review of a guy testing the waters on a $75 junkyard unit to see how tough it was. He put it in a 4000lb V8 Impala or Chevelle, did some drag launches that failed to hook up the tires (3.09 1st gear = mega torque / no traction), so he did the ultimate test that would always be sure to blow up several Muncie's he's had, holding the gas to the floor when shifting, resulting in 5000rpm shifts and chirping the tires in every gear, and the A833 MY6 survived quite well!

Also, this seems to be the same length as a Muncie, which if meant the same length as the Saginaw I have in mine, then I wouldn't have to have the drive shaft shortened whatsoever.

Only big drawback is that hard parts are tough to come by, only used... so running one of these for the long term would probably mean I would need to be scavenging junkyards to pull several of them to have gears/shafts parts available...
I gotta tell ya , I LOVE the MY6 NP440 tranny as I have it behind an 292 in my 66 GMC 3/4 ton and Im gonna put an 350 in it this season . BUT MAKE SURE you decide whether you want that one available in Aluminum case or Iron case . I decide to go w Iron because of something to do w/ the input shaft or something . But the Aluminum one can be fixed by putting an sleeve in it and it will be tough as heck . Here is a pic s
