Ok,
Withe the engine at TDC and the cams both aligned pointing at each other.

Whip the dist cap, rotor arm and splash shield off and look at the distributor body mounting face. (The part the cap contacts when its fitted.)

Towards the plenum side, there is a scribe mark in the body, and this signifies the phase alignment position at TDC. The centre of the rotor arm should point here mate.

If it doesnt, slacken the distributor body and rotate it until it does.

thats the crank / phase syncronisation mate.
