4 speed ka-booom !

Well a 100% true, slick shift, with no brass rings in it, and fully removed splines, certainly would be a PITA.They make semi-tractor trannys like that.
Which is why I mod mine the way I do, and leave the brass in. It works great for my little 367 cuber. I have to wonder why Chrysler didn't build them that way.With these mods it's as good a shifting 4-spd as any other out there. And IMO, better than the best of "back-in-the-day trannys.
Some of you might remember the Ford top-loader 4spds. Those were a pretty sweet shifting tranny. Well, from how I remember them,they got nuthin on an 833 modded the way I mod mine.
