[Shotimes] don's cams, a report

[Jim & Debbie Leyden]

Aren't there any other sets out there that have been installed and dyno'd?

This extremely disturbing!  I was considering getting a set.  I assume Doug
degreed one cylinder per cam.  If he had degreed
differences between cylinders, would the results show varying amounts of
advance/retard?  Wonder what the timing spacing between
cylinders looks like?  I hope we can learn the reasoning behind these
variances.  Inconsistencies of this amount are just not
acceptable for parts that command as high a price as these.

How many degrees of adjustment are available with the custom sprockets?

92 w/ a mod or two

If that is the case, why not exchange them for another
set? It seems like using adjustable sprockets won't
get them timed properly very easily. If they are
incorrect to start with adjustable sprockets will only
get you so far...

This is interesting. Keep us posted. My +20 cams are
installed in my 3.2 which is waiting to be installed
sometime this month.
