Ok so I have a RPM level 5 t56 with tick performance billet shift forks that I have been running for years in my my 68 firebird. I recently just got a good deal on a used t56 magnum F and dont know which transmission to keep or which one is stronger. Im thinking to sell the rpm trans and keeping the stock magnum but don't want to potentially break this magnum because its stock. What would yall do ?

 

I'm not sure what the level 5 T-56 comes with for gears, but if they're still T-56 gears, the Magnum-F is stronger. That's because it uses TR-6060 gears, or at least, it uses a gearset with the same width gears as a TR-6060.
