Default T-56 conversion???

I'm looking to put a T56 into my already V8 MGB. I wanted some question answered; I looked on here and could not find anything helpful with what I'm doing I don’t know if I just searched wrong or what. I have seen it done once before and the two bell housings were cut and welded together.

My MGB is a Rover V8 conversion with a Rover 5 speed (the trans sucks).

This is a shot in the dark but would anyone by chance know if the Rover clutch would match the input shaft on the T 56? The rover V8 is the same as a Buick 215 I’m hoping the GM based of the rover with help the mating of the T 56 to the Rover. So if not witch way would be the best to fix this, just find a clutch disk that fits the pressure plate and match the input shaft? Or use a T56 clutch and pressure plate and adapt it to the Rover flywheel.

I think I can handle the Shifter location. But can anyone give me the dimensions of the T 56 and possible the shifter location distance from the bell housing to the shifter

Does anyone know if there is a cable speedo hookup conversion for the LS1 T56? So I cold get it to work with the MGB speedo. Also what would have to be done with the skip shift being that it will not have the ECM anymore? I’m sure I will think of something else to ask!!!

This is an energetic project but certainly doable. I would suggest you not start with an Fcar T56. There is an aftermarket model ( 1386-000-012)that has a gear-driven speedo( Ford type that can be adapted to a cable-drive) You will have to fabricate a bell to accomodate whatever clutch/ releases systen you use. If you have a bell that mates to your Rover(Buick) engine , you can use it to fabricate a T56set up with a little cut/ weld.The above model is set up for a cable/fork release and is fairly simple to adapt The trans uses a 10t drive spline ( Fcars are 26t) that is very common . You should have little trouble getting a disc. You will not have to worry about any skip-shift issues . Good luck.
