last week driving home from work i noticed my car was making a strange noise, upon further invest. i found the source to be inside the cam housing on the rear side (left) of the motor. it sounds like a thwack every time the cam turns, the higher the rev, the louder and faster it gets, ive heard a rod knocking in an old 350 b/4 and it sounds different, but i still have yet to hear this noise... a buddy of mine said it may be a rocker off one of the cams? anyone have any ideas? a fast response would be nice, i need to tear into it in about 2 hrs when my help gets here

thanx in advance guys
