Hi, just starting on this project.  Have a 2002 Ram 3500 HO, (assumed since 6 speed) that someone put at 1998.5 (august 98) 215 SO engine in.  Runs like complete crap.  Idles great, but wont go over 60 mph.  Misses and stumbles off idle.  Has the persistent Cam Sensor performance code and the tach quits after 7 seconds of startup.  So have a 2001 gear, timing case and CPS on the way.  Also has teh correct 2002 MAP sensor.  Any tips or tricks? 

I've moved your post here so people would see it. 

 

As for your issue. You need to change the cam and gear case to fix the issue. What is happening is the cam gear has the wrong tone ring and the cam sensor will be in the wrong location when you change the cam. So most just change out the cam for the 2002 cam and then while the cam is out change the gear case.
