There is quite a bit of difference in transmissions too. If you were going to do the gearstart I would recommend you get in touch with Big Kev or Ross and pick their brains about adapting the 56 TU to the 54 engine as Kev is doing with his car.

The early gearstart had such limited field testing so various issues came about. There are some parts differences but It was almost identical to the 55 TU in valving and operation but we know those had their share of issues -- although many of those were due to the high HP engines. By 56 the bugs and valving had mostly been worked out. If you do that adapting of the 56 case and guts to the 54 bell housing, IMO you would be happier with the final product.
