That should be a clockwise motor but if your just trying to make sure motor is not lock up you can turn either way for short distance
Need to be careful about how to describe this, and from what vantage point you're viewing the engine.
- If you're standing in front of the engine, facing the pumps and belts, yes, they and the flywheel all turn clockwise.
- The 'rotation direction' of an
engine, however, is determined by facing it from the
rear. The standard GM V-block engine is a Left Hand/Counter Clockwise rotation engine.
If the OP needs to order a new starter, it may be important to know that he has a standard rotation (LH) engine. Seems to me I read one story here about someone getting a starter that spun in the wrong direction.
