It is clockwise, firing order is 1-5-3-6-2-4
counter clock wise
Pull off the cap and crank engine,Watch rotor! ----------------------------------------------------------- COUNTER CLOCWISE
The tail rotor is moving "perpendicular" to the main rotor, not "opposite". The tail rotor creates thrust opposite to the thrust of the main rotor, to keep the fuselage from spinning. Most helicopters spin the main rotor counter-clockwise looking from above, which puts a clockwise rotation on the fuselage. You need a tail rotor pushing the tail counter-clockwise to keep the fuselage pointed in the direction the pilot chooses.
Depending on the make of the helicopter, some will rotate clockwise and others will rotate counter-clockwise. However, the main rotor and tail rotor will spin opposite of each other. If the tail rotor spins clockwise, the main rotor will spin counter-clockwise. The main rotor also spins for lift, the tail rotor for control.
When viewed from the top, the distributor rotor in the 4.9L I6 engine turns clockwise.
If you are talking about the rear rotor (in the very back); it is used to counter the turning or yaw of the aircraft. The main rotor is turning in a certain direction and the rear rotor keeps the copter from just spinning around. The rear rotor can be adjusted to make the copter slowly turn.

Because it's supposed to. Some turn clockwise, some counter clockwise. Why? You would have to ask the design engineer but I suspect it has to do with patent rights. A Buick and an Olds. engine could be the same design and if the distributor turns in a different direction, it can be claimed as a different design.
Ford V8 engine - COUNTERCLOCKWISE Ford straight 6 cylinder engine - CLOCKWISE
Take the distributor cap off an crank the engine or turn the engine by hand clockwise and note the direction of the distributor rotor.
On the Ford 200 cubic inch straight 6 cylinder engine , the distributor rotor turns CLOCKWISE
To advance, rotate the distributor counter-clockwise. To retard, roatate it clockwise).
The first step is to turn off the engine. When installing, lift the cap to reveal the direction the metal tab is pointing on the rotor. Then remove the rotor for new installation.
