no thats wrong,this trucks timing is computer controlled you can move it but it wont make much difference at all i recommend you buy a superchips or hypertech if you want to do some tuning youll get the best bang for your buck with the most ease of installation instead of sitting there all day turning a distributor with no effect. you dont have to have coil over plug for it to be computer controlled


"The timing is computer controlled. No need for adjustments. If you've taken the distributor out it should go back in with the rotor pointing in the same direction as it was before removal. The hold down clamp is indexed to the distributor so it wont freely rotate just by loosening the clamp. There is a "sync" set procedure done with the drb scan tool used for Synching new parts when installed. Not used for maintenance adjustments though."
