GM was phasing out the use of the Borg-Warner T-10 in 1963, and the Muncie 2.56:1 ratio becamestandard equipment for four-speed applications in the 1964 Chevelle, Nova and Olds F-85/Cutlass. The early Muncie units built between 1963-'65 had a 7/8-inch input shaft and are not the best transmissions to use in a swap, but it is possible to use them with some changing of the internals.
