At the risk of being disliked, I will try and explain why a big block Mopar NEVER
needs a cam button. I don't know who started this useless idea, probably a Chevy
guy that decided to build a 440. If you look at the direction of rotation of the crank
shaft you will see that the crank drives the cam, which is pinned to the block by the
direction of the helical teeth cut in the cam. Besides this, the cam is also driving
the auxiliary shaft which drives the distributor and the oil pump. All of these things
are a load on the cam, sprockets, and chain. There is no physical way for the cam
to ever move forward when it is engaged with the auxiliary shaft. Just can't happen!
Save your hours of labor and don't waste your time with a cam button on a Big
Block Mopar. Thank You!
