One point I should make. Following conversions to Holdens, there grew the idea that the Series gearbox did not stand up to the additional power. However, it was eventually found that the gearbox failures were not the result of excess power, but of misalignment resulting from Holden adapter plates that were not made sufficiently accurate. Hence, After fitting the plate to the engine, the bell housing mating surface needs to be checked to ensure it is concentric with the pilot bushing and parallel to the flywheel face.
