    Q:
    How is lobe lift typically measured for the Camshaft of the 1987 Pontiac Fiero? Posted by Ala A.
    A:
    Lobe lift is measured by placing a dial indicator atop the cylinder head next to each pushrod and measuring the rocker arm's movement as it is pushed upward by the pushrod and cam lobe. You can Select Your Vehicle to see complete installation and repair tips.
