Ford Modular engine - Definition

The Modular engine, or MOD, is Ford Motor Company's modern V8 and V10 engine family. It replaced the Windsor small-block and 385 big-block engines 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 or Intech) and cars (called the Duratec). Ford recently introduced a 3-valve SOHC Variable Cam Timing system on this engine.

The engines are produced in Romeo, Michigan and Windsor, Ontario.

4.6

The first in the family was the 4.6 L (281 in³) SOHC V8 found in the 1990s Lincoln Town Car. Over the years, the 4.6 came in 2 valve and 4 valve versions (single and double overhead cam respectively). It has also come with both iron and aluminum blocks.

The aluminum 4-valve DOHC version was introduced in the 1993 Lincoln Mark VIII. It produced 280 hp and 285 ft.lbf and also featured a variable length intake manifold.

The engine was revised for 1999 with a better cylinder head, hotter cam, and better intake manifold. A 3 valve head with variable timing has been introduced for the 2005 Mustang. Bore and stroke are roughly square at 3.55 in and 3.54 in respectively.

The Modular DOHC was on the Ward's 10 Best Engines list for 1996, while the SOHC was on the list for 2005.

Vehicles using the cast iron 16-valve SOHC 4.6 include the following:

1991-1993 Lincoln Town Car, 190 hp

5.4

The 5.4 liter version is used in Ford Trucks and called the Triton. A reinforced Roots-type supercharged version powers the Ford F-150 Lightning and new Ford GT. The Triton was on the Ward's 10 Best Engines list for 1997 and 1998 and again for 2000 through 2002.

6.8

The 6.8 liter V10 is another in the modular family. It was created by adding a pair of cylinders to the center of the 5.4 L V8. It uses a balance shaft to smooth the vibrations present due to the added cylinders. Output was 265 hp and 405 ft.lbf, less than Dodge's Ram Tough V10, but close enough to counter the psychological effects of that V10's presence in the Dodge Ram trucks. The Ford V10 was used in 1997-2002 Ford Trucks as the Triton V10.
