milodon timing cover aluminum polished big block for chevrolet mark 4 1965-1990

Milodon aluminum timing covers feature either a highly polished or CNC-machined face. Their rigidity offers a positive, non-flexing cam stop. They are designed to fit over stock and double roller timing chains. They're also built to fit under stock short water pumps in most cases (some will require only minor water pump modifications). Milodon timing covers will not work with 4-gear style gear drives or belt drives.
