* Engine Orientation: The number 1 cylinder's location depends on how the engine is installed in the car (driver's side or passenger's side facing forward).
* Firing Order: Even if you knew the engine orientation, the cylinder numbering depends on the engine's firing order. The 305 engine could have different firing orders depending on the specific model year and options.
To find out the number 1 cylinder location:
1. Consult your car's owner's manual: This is the best source for this information.
2. Check the engine's casting: Look for a casting number on the block. You can then search online for a diagram showing the firing order and cylinder numbering for that specific casting.
3. Use an online resource: Websites like AllData or Chilton offer repair manuals with detailed information about specific car models.
Be careful: Working on a car's engine can be dangerous. If you're not comfortable working on your own car, take it to a qualified mechanic.
