[Healeys] Dwell angle for standard BN1 100/4

[David Porter]

Damn... I am losing it.. so, now the 38 degree thing is (in typical 
British fashion-opposite) the degrees that the points are open.
  Finally, if anyone has an easy way to determine the difference between 
a standard or high lift cam visually I'm all ears. Would also like to 
know the reasons for fitting different cams... I'm out of reading time 
for the day..
