Crystal ball is fogged up. We have no idea what engine you're working on.

If you can't get one for a 400, use the book for any year 426.

In summary:

  1. Line up the "I" on the flywheel (NOT the "H") with the timing mark.
  2. Install the exhaust cam with the "E" mark at 9:00 o'clock, aligned with the gasket surface of the head.
  3. Install the intake cam with the "I" mark at 3:00 o'clock, aligned with the gasket surface of the head.
  4. Retract, install, and release the tensioner.
  5. Recheck the timing.
