If you have an M20, you have wide ratio. M21 and M22 are close ratio. The M20 and M21 are basically the same except for the ratio. The M22 is heavy duty.

wowbagger,
NOT to confuse the situation but there is also the Borg Warner (now known as Richmond) Super T-10 (sometimes "listed" as a Muncie). The Early Muncies were also coarse spline and small output shaft while the later Muncie was a fine spline with a large (turbo 400) style output shaft. ...redvetracr

Re: gearbox question... (BB wowbagger)
I think wide ratio was standard....not positive though. You should have the Muncie. I believe the 74 was the first year for Super T-10's. There was a time where they were putting both transmissions in Vette in the same year. The Borg Warner trans is pretty much a copy of the Muncie. It's entirely possible that someone could have swapped your transmission, so the VIN might not be true.
