Gm used to to an endurance test on manual transmissions that they were using in their cars called the "Bonzai Test". EVERY manual transmission tested broke in LARGE pieces except 1 transmission...a Dearborn 3 speed!

IMO you'll have a lot more fun with a Muncie 4 spd and add value to your car too.

They are plentiful with lots of guys switching to automatics for better mileage, etc.
