context_page_description: The Ford Modular engine is Ford Motor Company's overhead camshaft V8 and V10 gasoline-powered small block engine family. The Modular engine received the name from its design and sharing of certain parts among the engine family, starting with the 4.6L in 1990 for the 1991 model year. The name was also derived from a manufacturing plant protocol, "Modular", where the plant and its tooling could be changed in a few hours to manufacture different versions of the engine family. The Modular engines are used in various Ford, Lincoln, and Mercury vehicles. Modular engines used in Ford trucks were marketed under the Triton name from 1997–2010 while the InTech name was used for a time at Lincoln for vehicles equipped with DOHC versions of the engines. The engines were first produced in Romeo, Michigan then additional capacity was added in Windsor, Ontario.
context_section_description: The 3-valve SOHC 4.6 L with variable camshaft timing (VCT) first appeared in the redesigned 2005 Ford Mustang.
  The engines are equipped with an electronic Charge Motion Control Valve (CMCV) system that provides increased air velocity at low engine speeds for improved emissions and low-rpm torque. Cylinder block material varies between aluminum used in the 2005+ Mustang GT and cast iron used in the 2005+ Ford Explorer and the 2006+ Ford Explorer Sport Trac (see below), though the same aluminum heads are used in all applications.
  The 3-valve SOHC 4.6 L engine was on the Ward's 10 Best Engines list for 2005–2008.
  Vehicles equipped with the 24-valve SOHC VCT 4.6 L include the following:
