Moroso Cam Button, Big Block Chevy - 60462

Professional engine builders are familiar with camshaft "walk" when excessive end play produces erratic spark timing and the timing chain/gear "eats" the timing cover Moroso solves the problem with a highly wear resistant button mounted in an aluminum holder and bolted to the cam timing gear by way of a retaining plate The button assembly does not allow the cam to "walk" forward, stabilizing ignition timing and preventing costly engine repair
