Muncie Transmission - C2

[brumbach]

If you were rebuilding a muncie transmission would you upgrade to a 1" pin or hold at 7/8"? What's the advantage of one over the other?

Thanks,

Bill

I dont know what the difference is but when I rebuilt my M20 behind my 420 hp 350....My guy stayed with a 7/8".....Sorry I dont have an explanation though.....

Not sure what pin your speaking of, But I had my M21 with a stock rebuild done by Ed Hartnet . He had to re-bush my case to eliminate a leak.


Cant say enough about what a pleasure it was doing business with Ed, I had the tranny done years ago by him and every time I see him at Carlisle he remembers my name and what he did to my trans,

I have a 427/425 car and the tranny is holding up fine with a stock rebuild

If over 300HP, then a definite yes.

Is such a conversion possible? What would it entail? I have a 1965 Muncie with the 7/8" cluster pin sitting around that I would like to rebuild someday, so I'm curious how this would work.

I don't do transmissions but I'm guessing that would be a good way to repair/update a leaking small countershaft pin case. You would need a 1" countershaft pin and a corresponding cluster [expensive] to go with your M20, 21 or 22.
