I still need the diameter of the lifter for the 4 cylinder engine for 
the guy doing the cam profile for my cam.  Does anyone have a Healey 100 
cam follower laying on the bench that they can get a quick measurement 
for me?

This is what I have Mike.

100 cam specs:
Lift 0.390"
Timing @ 0.021" 5, 45, 40, 10
Duration 230

100M (and S) cam specs:
Lift 0.435"
Timing @ 0.021" 10, 50, 45, 15
Duration 240

IMHO cam profiling has come a long way since the days when these were
developed and there are better profiles around now.
In our Targa engine we are running 0.485" lift
Timing @ 0.021" 49, 77, 77, 49. Duration 306 This engine still pulls 
very strongly from 1200 RPM.
