[Fot] TR3 Cam Failure

I have been helping a friend with his TR3 race motor and we keep braking cam
shafts . recently the cam broke between 1 and 2 cylinders while holding 5000
rpm through a sweeper. Comments seem to indicate that the 4 cylinder motor
is prone to breaking cams and a steel billet is required . I would
appreciate any comments on a similar experience and solution
