I recently put a fresh 360 into my Dart and it only has about 100 miles on it. It was making noise and running low oil pressure so I decided to pull the motor and inspect. Come to find out the cam/lifters are in very sorry shape. Some are chipped off on the corners and some are concaved so bad AND some of the plungers in the lifters are all the way down in their bore ( no spring pressure on them). I can shake those lifters and hear rattling around inside of them. Crower cam with compcams lifters. I followed the correct break in procedure and lifter preload was correct. I will include some pictures. PLEASE let me know what you guys think of what happened. Bad set of lifters??
