Had a cam break on a BDA, shifted from 5th to 2nd a bit too soon... Tell-tail on Stack tacho only goes as far 11,000

Broke the cam into 5 bits and broke a web on the cam carrier.
The engine builders quote was "Do you feel lucky ?" ... I was... Got away with a new pair of cams and a cam carrier on top of the normal scheduled rebuild (new valves / springs etc).
