68-69 M20 Muncie vs 77-78 T-10 M21 BW ?
These do interchange freely right? Which one do you prefer? Which is stronger?

I have not owned any T-10 cars but don't they use a larger TH400 sized output shaft?
If I run a old M20 in a 78 car , It should hook up like a th350 as far as driveshaft requirements and crossmember.

Super T-10's DO have the larger (TH400) outtput shaft & fine spline input.
Dimensionally they WILL interchange,same mount/crossmember,driveshaft length,etc. If you are in the habit of side-stepping the clutch pedal OR shifting WITHOUT IT,your Pontiac 400 or 455 is capable of breaking EITHER! The Super T-10s with the taller low gear ratio's ARE inherently WEAKER. SuperT-10's (for the most part) will be 10 years NEWER than MOST Muncies,so it's possible that you'll get a "tighter" or lower mileage unit. Muncies shift a little nicer/smother than the ST-10. |

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
