Ford V8 engine : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front
On a 1966 Ford 289 engine, the number one piston is located at the front of the engine on the driver's side. This configuration follows the standard firing order and cylinder numbering for Ford small-block engines, where cylinders are numbered from front to back, starting with the driver's side. Therefore, the first cylinder is on the left side when facing the engine from the front.

I was told the number 1 piston is at the back side of the motor closet to the passenger side.
