I have been screwing with AMC V8's since I bought my first AMX in 1975.
Every one that I have taken apart has had the same cam walk problem. I see that the bolt retaining the cam gear moves forward and grinds into the timing cover. Not too bad but bad enought to make shreads of aluminum. It is also apparent that the timing chain holds the cam back to some extend due to it's side load stiffness when new, but as the chain wears and flexes, the cam walks. I also think that stock and mild hydraulics seem to be less effected that HP profile cams with increase spring load. I see that Nick Alfano makes a cam walk plate sold on EBAY.
Anyone had any experience with this product, or is there something better.
