I have a old Cam Doctor I have played with a little. Mine is an
original (remember MS-DOS, card slots). The only advantage to the
Cam Doctor is that it is more accurate than a dial indicator and
degree wheel. I would say that most people will get the information
they need by manually profiling. Rather than measuring at equal
numbers of degrees, I find it better to measure at equal lifts. I
have a couple of pages on my website and an Excel spreadsheet you
can download. I have been told the spreadsheet is a little confusing
because with the typical degree wheel the scales go backwards and
forwards (BTDC, ATDC, etc.). You can check it out at <a

I hope it helps.<br>

How do I determine if a cam is good or bad. If
there are any marks on it does that make it bad. I
do know that two of the lifters has pitting on the
surface. <br>
