Re: Swap "granny gear" 4speed to a m20 4 speed muncie

Make sure if you do this swap for an aluminum case passenger car Muncie, you get the wide ratio and not the close. The close has a 2.2 first gear and required at least a 3.73 rear gear. And that was with shorter passenger car tires and usually MUCH more powerful engines.

And when talking 4 speeds, remember the truck granny 4 speed option id is ALSO M20 which was GM's designation for a wide ratio 4 speed manual trans option.
