Finally Starting My Engine Swap

[HO455]

You can double check it by turning the engine to TDC on the firing stroke and verify the rotor is pointing at #1.

With a new engine I like to pre-time the ignition by setting the timing mark on the balancer to about 8 degrees BTDC on the firing stroke. Then with a timing light hooked up rotate the distributor back and forth watching for the timing light to flash. ( You don't have to have the light pointed at the balancer.)
The rotor turns clockwise when the engine is running, so you want to turn the distributor counterclockwise when looking for the flash. It will take several tries to creep up on the flash to set the timing. If you go too far just turn the distributor clockwise and try again. You do need to have the distributor clamp snugged up for this work.

This will get the engine very close to the correct timing and the engine should fire right up.
