Where is 1 cylinder on a ford 360 engine?

The Ford 360 is a V8 engine, meaning it has two banks of four cylinders each arranged in a "V" shape. There isn't a single "cylinder 1". The cylinder numbering depends on which bank you're referring to and the orientation of the engine in the vehicle. Typically, the front-most cylinder on the passenger side (right side in North America) is designated as number 1, but you'll need a diagram specific to the engine's installation in the vehicle to be certain.
