The Modular engine is ) in Lincolns (called Intech) and in Ford and Mercury cars. In 2004 (2002 in Australia) Ford introduced a 3-valve SOHC with a Variable Camshaft Timing (VCT) system. The engines were first produced in Romeo, Michigan but additional capacity was added in Windsor, Ontario . 4.6 The first production Modular engine in the family was the 4.6 L (281 in³) 2-valve SOHC V8 introduced in the 1991 Lincoln Town Car . Over the years, the 4.6 came in 2-valve, 4-valve, And 3-valve versions ( Single- , Double- , and single-overhead cam respectively). It has also been produced with both iron and aluminum blocks. Bore and stroke are roughly square at 90.2mm (3.552") and 90mm (3.543") respectively. Deck heights for all 4.6 blocks are 227mm (8.937"). Connecting rod length is 150.7mm (5.933") center to center. This gives a respectable 1.67:1 rod to stroke ratio. Until 1999, all car engines were produced at the Romeo plant. In 1999 and 2000, Mustang engines were produced in Windsor. Production was moved back to Romeo in 2001. Most truck engines are from the Windsor plant, however there are many later model trucks with Romeo engines. All aluminum-blocked engines were produced at Romeo. While the basic design remains the same the two plants had different designs for main bearings, heads (cam caps), camshaft gears (press-on vs. bolt on), valve covers (number of bolts), crankshaft (number of flywheel bolts), and cross bolt fasteners for main bearing caps. The Modular DOHC was on the Ward's 10 Best Engines list for 1996, while the SOHC was on the list for 2005 and again for 2006. 2-valve ''Vehicles equipped with the cast iron 16-valve SOHC 4.6 include the following:''
Cracking manifold The original 2-valve engine, as used in the Lincoln Town Car , came with an aluminum intake manifold. However, the DuPont Zytel Nylon -composite Intake Manifold was used starting in the 1996 model year, and was found to crack at the front coolant crossover, leaking coolant and possibly causing engine failure. A Class-action Suit was filed on behalf of owners, resulting in a settlement announced on December 17 , 2005 . Starting with the 2002 model year, approximately 6-7 years after the inception of the all-composite intake, Ford finally began using a revised DuPont Zytel nylon-composite intake manifold with an aluminum front coolant crossover and replacement intakes were available for 1996-up engines. The following vehicles were included in this class-action suit settlement:
References: 4-valve The 4-valve DOHC version of the Modular engine was introduced in the 1993 Lincoln Mark VIII . The 1999 and earlier engines featured an aluminum block cast in Italy by Fiat subsidiary Teksid S.p.A. The engine was revised for 1999 with new cylinder heads featuring tumble-style intake ports, new camshaft profiles, and an improved, fixed runner length Intake Manifold . These changes resulted in not only more peak horsepower and torque but also a much broader powerband. ''Vehicles equipped with the all aluminum 32-valve DOHC 4.6 include the following:''

3-valve GT]] A 3-valve SOHC head with Variable Camshaft Timing (VCT) was introduced in 2002 in 5.4L form for the Ford Falcon (''Barra 230'') in Australia, and in 2004 for the Ford F-Series , as the new 5.4L '' Triton ''. The first 4.6L version appeared in the revised Ford Mustang (2005 model year). The engines are also equipped with an electronic Charge Motion Control Valve (CMCV) System that regulates the flow of air into one of the two intake ports (per cylinder). Block material varies between the aluminum block used in the 2005+ Ford Mustang and 2006+ Ford Explorer and the iron block used in the 2004+ Ford F-Series (see below), though aluminum heads are used in all applications. The 3-valve SOHC engine was on the Ward's 10 Best Engines list for 2005 through 2007. ''Vehicles equipped with the 4.6L 24-valve SOHC include the following:''
5.4 ]] See also Ford Triton Engine In trucks and SUVs the 5.4 L modular engine is known as the '' Triton '' or '' InTech ''. A 4-valve DOHC version was used in the limited production Cobra R in 2000, the Ford GT , the 2007 Shelby Mustang GT500 , and is used in the Ford Falcon line in Australia under the name ''Boss''. The Ford GT uses a highly-specialized version of the Modular engine. It is an all-aluminum Dry-sump 5.4 L 4-valve DOHC version with a Lysholm screw-type supercharger and it showcases numerous technological features, such as dual fuel injectors per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines. It is rated at 550 hp (410 kW) and 500 ft•lbf (678 N•m), though independent testing has shown these numbers to be conservative, with GTs often producing numbers similar to the manufacturer flywheel ratings at the rear wheels on chassis dynamometers. The Shelby GT500 uses a 4-valve DOHC version of the iron-block 5.4 L Triton with an Eaton M122H Roots-type blower and air-to-liquid intercooler. It produces 500 hp (373 kW) and 480 ft•lbf (651 N•m) (SAE J1349 certified). ]] See also Ford of Australia entry, below.

6.8 V10 The 6.8 L 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 initially 265 hp and 405 ft•lbf but output steadily increased over the years, eventually making 362 hp (266 kW) and 457 ft•lbf (620 Nm) with the introduction of the 3-valve SOHC version. The Ford V10 was used in the 1997 -present Ford E-Series vans, 1999 -present Ford F-Series Super Duty , and 2000 - 2005 Ford Excursion SUV s, as the Triton V10 . 5.0 CAMMER Mustang FR500C.]] In 2005, Ford Racing Performance Parts (FRPP) introduced a 5.0 L Crate Engine for use in Motor Racing and home-made performance cars, officially called M-6007-T50EA, but more widely known as "Cammer". Because the latest Mustang has only 3-valve heads, FRPP developed the Cammer from the previous generation's aluminum 4-valve DOHC engine. The Cammer that has seen success in Grand Am Cup — officially called M-6007-R50 — is fitted with a unique fixed runner length magnesium intake manifold, Ford GT aluminum cylinder heads, unique camshafts and an increased compression ratio, but the biggest difference is a 3.700" bore (3.552" is stock for modulars) achieved by resleeving the alloy/aluminum block. The 5.0 L Cammer is used mainly in Mustang racing cars in the Grand-Am Cup and the SCCA World Challenge 's GT class, but can be installed in a variety of other applications, including road cars, Dragster s and Sports Car racing prototypes. Upon introduction the Cammer-powered Mustang proved to be dominant in Grand-Am Cup, having achieved five victories and podium appearances in nearly every race in the GS class during the 2005 season, giving David Empringham the championship title with the Multimatic Motorsports team, and Ford the manufacturer's title. Robert Yates publicly expressed interest in using a similar 5.0 L 4-valve DOHC Modular V8 to compete in the NASCAR Winston (now NEXTEL ) Cup series. ''Robert Yates on Modulars in Winston Cup.''

FORD OF AUSTRALIA Ford Australia uses modular V8s in the Ford Falcon and Ford Fairlane sedan model ranges, as well as in its high performance Ford Performance Vehicles (FPV) division models. The DOHC Modular V8s are coined ''Boss'' by Ford Australia, with a number designation referring to power output in kW. The SOHC 230 kW ''Barra'' engine and Boss 260 and 290 shortblocks, heads and crankshafts are built in Windsor, Ontario. The Boss engines include some locally sourced parts such as intake and pistons. All are built with cast-iron blocks. ''Ford of Australia 5.4 L engines include:''
