Sorry I missed the beginning of this thread.

These are the same cam specs as the Crane 2030. I know of 2 people that
have this cam. One is not happy with it because he lost too much low end.
The other is happy with it but he has a Powerdyne SC. Both are Durango
owners with the 5.9L engine.

>From the dyno simulations I have run (on the 5.9L) with Engine Analyzer 3.0b
this cam is worse than stock all the way up to 4000 RPM. The cams produce
the SAME HP/TQ numbers at 4000 and the 2030 is better at 4500 and above.

I have run the following cams and none of them are better than the stock cam
until you cross 3500+ RPMs: Crane 2020, 2030; Hughes 0612AL; Comp 20-602-8,
20-604-8, 20-608-8; Lunati 50416, 50417, 50418. I was not able to get a
complete set of specs from Crower or Mopar so I was not able to run those
cams on the simulator. Again this is a computer simulator and reality is
often different, but this should be a good test as all the cams were faced
with the same program deficiencies.
