The CSX: January 15, 2006

For reasons I don't quite understand, the #4 exhaust cam and follower got trashed.  The valve train was making some horrible sounds when I got home from the meeting last night.  I swapped the FM475 cam with an '88 TBI roller cam.  Also put in the PT Cruiser followers.  The valvetrain is very quite and the lope at idle is gone.  Idles real smooth, but runs a little rich now and lost some bottom-end and midrange torque.  Pulls OK at the top end.  Need an adjustible cam sprocket, as I can't remember if the donor car had the square tooth or round tooth sprocket.
