To check if your distributor is installed backwards on a 1972 Plymouth Cuda with a 318 engine, first ensure the rotor is pointing toward the number one cylinder when the engine is at top dead center (TDC) on the compression stroke. If the rotor points away from the number one cylinder or is misaligned, the distributor may be installed incorrectly. Additionally, verify that the distributor gear is properly engaged with the oil pump drive. If you encounter difficulty in aligning the rotor with the number one cylinder, it may indicate that the distributor is reversed.
On a 1972 Datsun 240Z, the number 1 cylinder is located at the front of the engine, closest to the radiator. The engine in the 240Z is an inline-six configuration, so the cylinders are numbered 1 through 6 from front to back. Thus, cylinder 1 is at the far left when facing the engine from the front of the car.
