I'm not trying to ruffle feathers here, but the Q engines are the flywheel forward models. The F models are flywheel rearward in normal manner. The Q engines have a Chris Craft firing order that is not related to any SBC engine. The number one cylinder is at the front of the engine on its left side as viewed from aft in Q installation. The distributor rotates clockwise. Q engines time at 10°@ 500 RPM. Q engines have dimples in the flywheel for both Right hand and Left hand rotations. The dimples are marked R and L accordingly. A starboard Q engine rotates in normal engine manner whereas a Port Q engine rotates reverse. Starboard Qs have timing chains. Port Qs have timing gears.Port Q engine distributor also rotates clockwise with a different firing order. J.The 1968 23 Commander came with 327F or 427. The 327F is installed backwards, with flywheel forward, and must spin the transmission Left Hand in order to make the prop spin Right Hand. Therefore the F is a Right Hand (otherwise known as Opposite Rotation) motor.
The 1969 23 Commander came with 327Q or 427. The 327Q is installed frontwards, with flywheel aft, and is mated up to the transmission at what we will call the "front" of the motor. Therefore it is a Left Hand motor because it too must spin the transmission hub Left Hand in order to make the prop spin Right Hand.
