What axle ratio? DSO?

Info can be found on the driver's door below the striker latch. WARNING: Make sure the warranty plate matches your truck and registeration.

But from what I'm reading:

Curb idle RPM: 650 RPM

Spark plug: Motorcraft ASF-42 (now ASF42C)

Spark plug gap: .042-.046

Timing: 8- BTDC
