Moroso 60461 - Cam Button, SBC, Late Cover

• 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
