If you want to keep it stock (Like) you could install an aluminum case Muncie 4-speed M-20 - or a close ratio M-21 or a heavy duty close ratio M22.

Or you could go with a cast iron case Saginaw.

I'd go Muncie,

Or you could go G-Force
Or
Lenco

Did a search and found this tidbit on transmissions.
* The M20 4-speed, standard transmission, RPO was a generic category. It was translated at the factory into a low-performance Saginaw when teamed with the L6 engine, as the higher-performance Saginaw in the low-end V8s, and as a Muncie in the SS and Z28 models.
* The M40 3-speed, automatic transmission, RPO was also a generic category in 1969. It was translated at the factory into the moderate performance THM350 (actually RPO M38) for non-big-block engines, and into the THM400 for big-block engines.
* The base 3-speed standard transmission for the SS-350 in 1967-68 was the 3-speed, column-shift, Saginaw. And it was only available in the column-shift. If a floor-shifted 3-speed was desired, the M13 HD three-speed, available only in floor-shift, was a separate option. The base SS-350 (and LM1) 3-speed was changed to the floor-shifted HD version in 1969 - the column shift standard transmission was no longer available in the SS or LM1 cars.
* The HD three-speed standard transmission was RPO M13 in 1967-68 (manufactured by Warner), but was MC1 (manufactured by Muncie) in 1969.
* A floor-shifter for automatic transmissions was only available with the D55 console. Except the 1968 L35/L34 396 engines with the THM400 transmission, for which a non-console M11 floor-shifter was available. (Note: the CRG would be interested in hearing from anyone with a 396/M40 with a non-console floor shifter.)
* The MB1 "Torque-Drive" two-speed transmission was only available for the L6 engines, and only in 68-69.
