It would depend on how each is made, the shorter tube will have a higher yield than a longer one but normally longer tubes are larger diameter. A 3" chromoly tube has a max yield of 4957 compared to a 3-1/2 aluminum shaft at 3464. Being the engine/trans would
have a hard time reaching either its a draw in my opinion. Lingenfelters car although runs our axles still has the factory shaft, the Guibo
