I don't know if you are talking about just setting the timing or replacing the dist or what. The timing is not adjustable. If you have the dist out and are trying to put it back in, here it is.

Pull #1 spark plug and put you finger over the hole so you can see when that cyl starts on comp stroke. Have someone bump the starter and when you feel preasure, turn the engine by hand to where the timig marks on the balancer is at top dead center. Install your dist so that the rotor is pointing streight foreward when it is fully seated and put #1 spark plug wire at that tower on the cap. Then put the rest of the wires in order 1-8-4-3-6-5-7-2 going clockwise around the cap. #1-3-5-7 cylinders are on the drivers side.

95 truck man

if truck is a 95 or earlier,the timing is adjustable.warm motor to operating temp.loosen dist. holddown bolt.then find the connector for the timing by-pass,(tan wire with a black stripe)usually on the fire wall or under the glove compartment.unplug this wire,start motor,check timing with a timing light,move advance or retard timing.tighten dist.bolt and plug tan wire back in.This will set a check engine light.pull the fuse or fuses for the ECM for 10 minutes and reinstall fuses.this will reset the ECM.or,you can unhook the battery cables to reset the ECM,but this will wipe out radio presets ,etc.

Please note that if you are setting the initial ignition timimg on a throttle body 305 or 350 engine you must disconnect the ecm plug located on the top left of the firewall, next to the black cover labeled relays and or fuses. What this does is take the ecm out of the equation during the inital timing process. If you don't setting initial timing will never be correct. Initial timing should be set at zero degrees before tdc, after that is done, tighten the dist hold down bolt and reconnect the ecm plug.
