there is a mark on the Distributor casing .
As you look at it from the front of the car and from above
at the 2 o'clock position.
line up the Distributor Rotor arm with that.
while keeping the Crank pully mark inline with the mark on the block,
and the two Arrows on the cam pullys pointing exactly towards
each other..
when all the arrows and marks line up.
its at standard timing mate!!
