    Hey Everybody,

    I just want to double check something. To get the advance intake 6* and the retard exhaust 6* , a person ON THE CRANK, WITH THE CAM GEARS LOOSE, with a degree wheel, the balancer at the mark and the degree wheel on 0, would have to turn (clockwise) the crank to 6* BEFORE TDC, LOCK CAM GEAR ON THE INTAKE and then turn the crank to 6* AFTER TDC, and lock the CAM GEAR ON THE EXHAUST? (on the same rotation for front cams)

    Then I can rotate the crank 2 rotations and put the balancer on the mark and loosen the arms on the cam adjustment tool ( I was doing this cause I don't know where +3/-3 is on the tool) and tighten the arms where they sit with the tool tightened to the cam carrier.
    I then have my tool set to true +3/-3 and cam just turn the engine 1 rotation and put the tool on the rear cam carrier and tighten both Cam gears. DONE.

    I just want to be 100% sure.... I don't like being a know it all.........

    Thanks!!!

      Thanks Ben!!!

      I just like being sure that I've got things right.

      Basicly the arms on the tool will be slightly tilting inward toward each other.


      Setting the Cam gears is easy on these brand new cam carriers cause what was neat is the new 1991 cam carrier set comes with the cam gears that are on the late models without those dumb rings.

      I'll have to take some pics.
