Installation:

  2. Remove distributor and valve cover.
  3. You will need to remove the front cam bolt in order to remove the distributor drive gear and the stock fuel pump eccentric. Make sure you support the cam gear and chain to prevent it from accidentally falling and causing the chain to skip a tooth.

  5. Torque cam bolt to 62ft-lbs.
  6. Install valve cover and distributor.
  7. Reset ignition timing.
