1 Align the indent hole on the driven gear with the paint mark on the distributor housing
Ensure that the distributor rotor segment points to the cap hold area
2 Align the slotted tang in the oil pump driveshaft with the distributor driveshaft. Rotate the oil pump driveshaft with a screwdriver if necessary
3 Install the distributor and distributor clamp. The flat in the distributor housing must point toward the front of the engine.
4 Once the distributor is fully seated, align the distributor rotor segment with the number 6 pointer (1) that is cast into the distributor base. 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
The flat in the distributor housing must point toward the front of the engine

Timing is off the #1 piston.
#1 piston at TDC on compression stroke. Drivers side, furthest from the driver.
I dropped my distriburator in so that the rotor points to the #1 piston.
