Is my 2001 ford f150 Triton motor 2 or 3 valve?

The 2001 Ford F-150 equipped with the Triton V8 engine typically has a 2-valve configuration. The 3-valve version was introduced in later models, starting in 2004 with the 5.4L engine. If your F-150 has the 4.6L V8, it also features a 2-valve design. You can verify this by checking the engine code or specifications in your owner's manual.
