A 3-valve
SOHC head with variable timing was introduced in
2004 in the
Ford F-Series. Block material varies between the
aluminum block used in the 2005+ Ford Mustang and the
iron block used in the 2004+ Ford F-Series and 2006+
Ford Explorer, though aluminum heads are used in all
applications.
The 3-valve SOHC engine was on the
Ward's 10 Best Engines list for 2006.
Vehicles using the 3-valve
SOHC version include:
Ford Modular engine
|
Ford Modular V8 |

The Modular engine, or "mod motor" as
it is often referred to, is
Ford Motor Company's modern
overhead camshaft (OHC)
V8 and
V10 engine family. It gradually replaced the
Windsor
small-block and
385
big-block engines over several years in the
mid-1990s. The engine is modular in that it can be
adapted to V8 or V10 with a variety of 2-valve and
multivalve heads. It is used in Ford trucks, (called
the
Triton) in Lincolns (called Intech) and in Ford and
Mercury cars. In 2004 Ford introduced a 3-valve SOHC
with a
Variable Cam Timing system, this engine will
eventually phase out the 2-valve SOHC, although it has
replaced a 4-valve DOHC engine, at least temporarily, in
the
Lincoln Navigator.
