Important: The engine front cover has 2 alignment tabs and the crankshaft balancer has 2 alignment marks (spaced 90 degrees apart) which are used for positioning number 1 piston at top dead center (TDC). With the piston on the compression stroke and at top dead center, the crankshaft balancer alignment mark (1) must align with the engine front cover tab (2) and the crankshaft balancer alignment mark (4) must align with the engine front cover tab (3).
Rotate the oil pump driveshaft with a screwdriver if necessary.
The flat in the distributor housing must point toward the front of the engine.
If the distributor rotor segment does not come within a few degrees of the number 6 pointer (1), the gear mesh between the distributor and camshaft may be off a tooth or more. Repeat the procedure again in order to achieve proper alignment.
Tighten Tighten the distributor clamp bolt to 25 N·m (18 lb ft).
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten Tighten the distributor cap bolts to 2.4 N·m (21 lb in).

you need to take out the #1 plug,,,hold your finger on the plug hole...have your help to bump the starter till you feel air[compression]start to come out of the hole....then hand turn the engine until the mark on the harmonic balancer is on [o]..now you have the #1 piston up on the compression stroke...now,install the distributer to where the rotor is pointing to the #1 plug wire terminal...now it is in time
you align it up with the terminal on the inside of the cap that gos to the #1 plug wire
the #1 plug wire terminal is on the drivers side in the middle....turn the distributer cap over and follow the worming of the #1 to the rotor contact teminal.....you need to install the distributer with the compression up on the #1 cylinder with the rotor pointing to the #1 rotor contact teminal so it would be sending power to the #1 plug wire
