Hi, I posted here about a week ago with a question abotu why my distributor gear was chewed up. I have come to the conclusion that my cam is walking. How and why does this happen? The engine is a 289 with a comp cams mechanical lifter cam, cloyes double roller timing chain(the one with the spacer on the back). I think that that was all I changed when I switched cams, beforre the swap there were no problems. How do I fix this? Thanks.
