In 1999, Ford introduced the DOHC 4-valve 5.4&nbsp;L in the [[Lincoln Navigator]] under the ''InTech'' moniker, making it the second engine to use this name. Ford later used versions of the DOHC 4-valve 5.4&nbsp;L in the 2000 [[Ford Mustang SVT Cobra#2000 Cobra R|Ford Mustang SVT Cobra R]], the [[Ford GT#First generation (2005–2006)|Ford GT]] [[supercar]], and the [[Shelby Mustang#2007|Ford Shelby GT500]]. The DOHC 4-valve 5.4&nbsp;L was also used in the [[Ford Falcon (Australia)|Ford Falcon]] line in Australia under the ''Boss'' moniker until 2010, when it was replaced by a locally developed, supercharged version of the 5.0 litre Modular V8.{{citation needed|date=October 2012}}

The SVT Cobra R version of the 5.4&nbsp;L 4-valve V8 had several key differences from its Lincoln counterpart. While the iron block and forged steel crankshaft were sourced directly from the InTech 5.4&nbsp;L, the Cobra R powerplant benefited from new, high-flow cylinder heads that were designed with features developed for Ford's "Rough Rider" off-road racing program, application specific camshafts with higher lift and more duration than other 4-valve Modular cams, forged I-beam connecting rods sourced from Carillo, forged pistons that provided a 9.6:1 [[compression ratio]] in conjunction with the 52&nbsp;cc combustion chambers, and a unique high-flow "cross-ram" style aluminum intake manifold. The Cobra R was rated at {{cvt|385|hp|kW|0}} and {{cvt|385|lbft|Nm|0}} though chassis dynamometer results have shown these ratings to be conservative with unmodified Cobra Rs often producing nearly {{cvt|380|hp}} at the rear wheels.<ref>{{cite news |url=http://www.motortrend.com/roadtests/112_0008_2000_viper_cobra_r_and_corvette/viewall.html |title=2000 Dodge Viper vs. 2000 Ford Cobra R – Detroit Muscle 2000 |work=Motor Trend |access-date=2011-08-30 |archive-url=https://web.archive.org/web/20120109052730/http://www.motortrend.com/roadtests/112_0008_2000_viper_cobra_r_and_corvette/viewall.html |archive-date=2012-01-09 |url-status=dead }}</ref>

The Ford GT version of the {{cvt|5409|cc|L CID|1|order=flip}} is a highly specialized version of the Modular engine. It is an all-[[aluminum alloy]], [[dry-sump]] [[Overhead camshaft#Dual overhead camshaft|DOHC]] [[Multi-valve#Four-valve cylinder head|4 valves]] per [[Cylinder (engine)|cylinder]] with an [[Eaton Corporation|Eaton]] 2300 [[Rotary-screw compressor#Superchargers|Lysholm screw-type]] [[supercharger]] and showcases numerous technological features, such as dual [[fuel injector]]s per cylinder and oil squirters for the piston skirts, not found in other Ford Modular engines of the time. This engine benefits from an improved version of the high-flow 2000 Cobra R cylinder head and unique high-lift [[camshaft]]s, now rated at {{cvt|550|bhp|PS kW|0}} at 6500&nbsp;rpm and {{cvt|500|lbft|0}} at 4500&nbsp;rpm.<ref>{{cite web |url=http://media.ford.com/article_display.cfm?article_id=17670 |title=2005 Ford GT Will Deliver 550 Horsepower in Production Trim |publisher=Media.ford.com |access-date=2013-03-11 |url-status=dead|archive-url=https://web.archive.org/web/20041212163814/http://media.ford.com/article_display.cfm?article_id=17670 |archive-date=2004-12-12}}</ref><ref>{{cite web|url=https://www.carfolio.com/specifications/models/car/?car=110594|title=2005 Ford GT|website=carfolio.com|date=2013-02-28|access-date=2018-07-27}}</ref>

The Shelby GT500 uses a 4-valve DOHC 5.4&nbsp;L with an Eaton M122H [[Roots type supercharger]] and air-to-liquid intercooler.<ref>{{cite web|url=http://www.windingroad.com/features-page/ford-engines/ |title=Ford Engines – Technical Focus – Winding Road – September 2006 :: Winding Road |access-date=2008-04-04 |archive-url=https://web.archive.org/web/20080222195547/http://www.windingroad.com/features-page/ford-engines/ |archive-date=2008-02-22 |url-status=dead}}</ref> The GT500 5.4&nbsp;L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra; which have less lift and duration than the Ford GT camshafts. The 2007–2010 GT500 engine used an iron engine block, while the 2011 GT500 5.4&nbsp;L receives a new aluminum engine block, with Ford's first production application of their patented [[Plasma Transferred Wire Arc]] (PTWA) cylinder coating, eliminating the need for pressed in cylinder liners. The PTWA spray apparatus was co-developed by Ford and Flame-Spray Industries of Long Island, New York, for which they received the 2009 IPO National Inventors of the Year Award.<ref>{{cite web |url=http://www.ford.com/about-ford/news-announcements/press-releases/press-releases-detail/pr-energyefficient-engine-technology-30443 |title=Energy-Efficient Engine Technology Wins Ford Team National Inventor ... – Press Release |publisher=Ford |access-date=2010-04-15 |url-status=dead|archive-url=https://web.archive.org/web/20090608003121/http://www.ford.com/about-ford/news-announcements/press-releases/press-releases-detail/pr-energyefficient-engine-technology-30443 |archive-date=2009-06-08}}</ref> The 2011 GT500 engine weighs {{cvt|102|lb}} less than the previous iron-block version, thanks in part to the lack of cast iron cylinder liners.<ref>{{cite web |url=http://autosfans.com/2011-ford-shelby-gt500/ |archive-url=https://archive.today/20120707024121/http://autosfans.com/2011-ford-shelby-gt500/ |url-status=dead|archive-date=2012-07-07 |title=2011 Ford Shelby GT500 |publisher=Autos Fans |date=2010-02-08 |access-date=2010-04-15 }}</ref> All of the 5.4&nbsp;L 4-valve engines destined for use in [[Special Vehicle Team|SVT]] vehicles, such as the Ford GT and Shelby GT500, have been hand-built by technicians at Ford's [[Romeo, Michigan]] plant.<ref name=autogenerated1 />
