Ford has changed the 2002 engines...
I copied this from a online SVT course that i was taking tonight.
The mainstream F-150 is updated for 2002, and some of the updates are carried over to the Lightning.
The engine block is strengthened in both the F-150 and the Lightning.
The front cover is updated for the F-150 but the front cover on the Lightning vehicles are not. The reason for the update of the front cover in the F-150 is the front pulleys are 6K pulleys (formerly 8K). The Lightning still uses the 8K pulleys.
The term "8K pulley" refers to the number of grooves in the pulley. The Lightning has 8, the F-150 has 6.
The Lightning uses the 8K pulley for improved NVH and durability.
The crankshaft position sensor and pulse wheel have both been updated in the F-150 and the Lightning.
The 1998 and 1999 5.4L engine in the Lightning used the same cooling fan as the production 6.7L engine.
Research indicated that the 5.4L fan provided better cooling.
As a result, 2000-2002 Lightnings use the 5.4L fan, and the crankshaft damper and threads in the water pump were revised to accept the updated cooling fan.
Another difference between the mainstream F-150 and the Lightning is that although the knock sensors are correctly wired in the engine the knock sensors are not used by the PCM.
