First off put the engine at tdc on no 1 .
Remove distributor cap.
Mark the distributor where it attaches to the head and the head, to be used as a reference point.
make note of where the rotor button points.
Undo the wiring.
Unbolt the dizzy.
Pull the dizzy out, the rotor will turn slightly.
Put the new dizzy in with the rotor facing the same location as where it finished turning to. when the dizzy is all the way home the rotor should face, the same location as previously noted. if not do this step again until correct.
Now place the dizzy housing in the same location as you marked in the first step.
Connect wires and refit cap.
Car should start
recheck timing, should be near enough to perfect if steps carried correctly.
Timing should be 15 degrees btdc
There is no substitute for cubic inches but my pursuit sure closes the gap
