This will be for a 289 model, I should have added that.
I have a TKO 600 for my Hurricane but with the 289, I want to use something closer to the original top loader but with an overdrive. I have the same rear end ratio as you cobred, 3.31 in a 4HU.
Is the T56 6 speed physically larger than say, the TKO? I'd like to try and keep the shifter in the original 289 location. I've just started looking at the Richmond 5 speed.
