..... The factory put Borg Warner Super T-10's in the '84-'88 vettes … except they hung a Doug Nash overdrive unit on it and called it a 4+3 … to put a Muncie in you just need to figure out what to do with the C-Beam … and then you need to learn to live with final drive ratios at highway speeds vs getting your lump moving from a dead stop … Muncie 1st gear ratios are 2.20 for the close and 2.52 for the wide while the 4+3 used a 3.06 1st gear …..
