Ok, so I have a 77/78 Chief. 360/th400. Since I've been driving it I've been trying to trace all of the odd sounds it has. One that I'm still having trouble with I's a rocker arm tick. I had one shop try to tell me it was a bad wrist pin...I have pulled the valve covers roughly 4 times and every single time I manage top find some of the rockers loose. The motor was rebuilt looking ago but still fresh, 60k. It has said studs but no bridges, tried to buy and install then and they don't fit...it has oblong locking nuts with no washers tisk are very hard to remove and tighten, but when I manage to, the rockers do go quiet. For about 5 minutes...I don't know too much about amc motors so I'm a little lost...also the motor feels stronger than 140hp and it revs to about 4600. I'd like to swap over to full rollers as well.
