[Shotimes] don's cams, a report

[Bruce Malachuk]

I'm going to the dyno on october 15th.

Side by side to a 3.2L MTX with all the same boltons as I have minus UDPs
and a tweecer (untuned at the time) I easily pull away from my friend from a
roll. And he's also 80lbs less tubby than me. I planned on pulling my motor
over the winter in favor of building a FI motor, and if when I do that I
would spend the time to degree my cams and see where they line up. I know my
car screams at 4300+ with my +20's

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?

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.
