Hi there,
I am about to embark on a heart transplant (engine that is!)

Changing the orginal M10 engine for the M42 engine
The car will be mainly used for road use, but also some track days.
What would you do on a complete engine strip and re-build, modyfying any faults, that over the years have been recognised and corrected.
Also, performance of the engine will be sensibly played with :cool:, any sugestions?
