The '''Ford SHO V6''' is a family of [[DOHC]] [[V6 engine]]s fitted to the [[Ford Taurus SHO]] from 1989 to 1995. The designation SHO denotes '''S'''uper '''H'''igh '''O'''utput.<ref name="G1">{{cite web|publisher=Taurus Car Club of America |url=http://www.taurusclub.com/encyclopedia/G1/index.html#1989 |title=Taurus/Sable Spotter's Guide (Generation 1, 1986-1991)#1989 | archiveurl = https://web.archive.org/web/20080411113954/http://www.taurusclub.com/encyclopedia/G1/index.html#1989 |archivedate=2008-04-11 |url-status=dead }}</ref>  

Due to the engine's unusual and aesthetically pleasing appearance it is sometimes transplanted into other vehicles. Its distinctive [[variable length intake manifold]] is bilaterally symmetrical, so it can be rotated 180 degrees (making it face "backwards" on the engine, relative to its original installation orientation) to ease the engine's transition from [[Transverse engine|transverse]] to [[Longitudinal engine|longitudinal]] mounting.<ref name="SHO37Ford">{{cite journal| last =Tann| first =Jeff| title =Vargas' Beauty: Smooth, Shiny, Intoxicating & Exotic Describe This '37 Ford Coupe| journal =[[Rod and Custom]]| issue =March 1999| pages =115–118 }}</ref><ref name="SHORod">{{cite journal| last =Boughn| first =Warren| title =SHO Time: Installing a SHO Taurus Engine in a Street Rod| journal =[[Rod and Custom]]| issue =May 2000| pages =121–124 }}</ref><ref name="SHO37FordCopy">{{Cite web|url=http://www.kurtmetros.com/37Ford1.html|title=SHO 37 Ford article copy | url-status = dead | archiveurl=https://web.archive.org/web/20110713174026/http://www.kurtmetros.com/37Ford1.html|archivedate=2011-07-13}}</ref><ref name="SHORodCopy">{{Cite web|url=http://www.kurtmetros.com/transplant1.html|title=SHO Rod article copy |url-status=dead|archiveurl=https://web.archive.org/web/20110713174100/http://www.kurtmetros.com/transplant1.html|archivedate=2011-07-13}}</ref><ref name="SHOTransmissions">{{Cite web|url=http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=article&mode=thread&order=0&thold=0&sid=176 |title=SHO engine with other Ford Transmissions |url-status=dead |archiveurl=https://web.archive.org/web/20120314032001/http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=article&mode=thread&order=0&thold=0&sid=176 |archivedate=March 14, 2012 }}</ref><ref name="SHOHealey">{{Cite web | url = http://www.britishv8.org/other/normanrest.htm|title=SHO V6 in a Healey|accessdate=2012-08-17}}</ref>

The SHO engines share a common [[bell housing]] pattern with the following Ford engines: the 2.3/2.5&nbsp;L FWD [[Ford HSC engine|HSC]] I4, the 3.0&nbsp;L FWD/RWD [[Ford Vulcan V6 engine|Vulcan]] V6, and the 3.8&nbsp;L FWD [[Ford Essex V6 engine (Canadian)|Canadian Essex]] V6.<ref name="FordBellhousings">{{Cite web|url=http://www.mercurycapri.com/technical/trans/general/tbhi.html |title=Wayback archive of Ford Bellhousing information site |archiveurl = https://web.archive.org/web/20030907134826/http://www.mercurycapri.com/technical/trans/general/tbhi.html |archivedate = 2003-09-07}}</ref> In 1996, Ford discontinued the SHO V6 and began fitting the Taurus SHOs with the SHO [[Ford SHO V8 engine|3.4&nbsp;L V8]] and the [[Ford_AXOD_transmission#AX4N|Ford AX4N]] [[automatic transmission]].

== Origin ==
In 1984, executives of the [[Yamaha Motor Corporation]] signed a contract with the [[Ford Motor Company]] to develop, produce, and supply a compact 60° [[DOHC]] V6 engine based upon the existing Vulcan engine for [[transverse engine|transverse]] application.<ref name="SHONTELL">{{cite web|url=http://www.fordmuscle.com/archives/2005/08/SHOnTell/|title=SHO n Tell|publisher=Jon Mikelonis and Matt Wilder|accessdate=2008-04-04|archive-date=2011-04-26|archive-url=https://web.archive.org/web/20110426023801/http://www.fordmuscle.com/archives/2005/08/SHOnTell/|url-status=dead}}</ref><ref>{{cite video | people = Ford Motor Company | title = 1989 Ford Taurus SHO commercial | publisher = Ford Motor Company | url = http://www.retrojunk.com/details_commercial/4176/ | date = 2007-07-19}}</ref>

== 3.0&nbsp;L ==<!-- This section is linked from [[Ford Taurus]] -->

The SHO V6 was a high-tech and revolutionary design when it debuted in 1988. Displacing {{cvt|2986|cc|L cuin|1|order=flip}}, it was an iron block, closed deck, aluminum head 24-valve DOHC engine with an innovative [[variable length intake manifold]]. Its [[oversquare]] and symmetrical design, which sported an {{cvt|89x80|mm|in|2}} bore and stroke, gave the high-revving engine an output of {{cvt|220|bhp|kW PS|0}} at 6200&nbsp;rpm and {{cvt|200|lbft|Nm|0}} of torque at 4800&nbsp;rpm at the [[flywheel]], and it sported the added luxury of being able to be used in rear-drive applications. [[Redline]] was marked on the [[tachometer]] at 7000&nbsp;rpm, and fuel cut-off occurred at 7300&nbsp;rpm. This engine was only available with the Ford [[Ford MTX transmission|MTX-IV]] transmission.

== 3.2&nbsp;L ==<!-- This section is linked from [[Ford Taurus]] -->

From 1993 to 1995, the SHO engine was sold in two displacements: the existing {{cvt|2986|cc|L|1|order=flip}} continued to be sold mated to the MTX-IV [[manual transmission]], and a new {{cvt|3191|cc|L cuin|1|order=flip}} engine was sold mated to the [[Ford AX4S transmission|Ford AX4S]] automatic transmission. The new {{cvt|3191|cc|L|1|order=flip}} engine, while retaining the same {{cvt|80|mm|in|2}} stroke of its {{cvt|2986|cc|L|1|order=flip}} brother, sported a larger {{cvt|92|mm|in|2}} bore that helped raise torque output to {{cvt|215|lbft|Nm|0}} at 4000&nbsp;rpm at the flywheel.<ref name="shotimes.com">{{Cite web|url=http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=article&mode=thread&order=0&thold=0&sid=24|title=Specifications|accessdate=2010-07-04|work=shotimes.com}}</ref> Power output was still {{cvt|220|bhp|kW PS|0}}, but now at 6000&nbsp;rpm; this was due to a milder cam setup compared to the more aggressive intake camshaft in the {{cvt|2986|cc|L|1|order=flip}} version.

== Other Ford vehicles ==

In 1989, with the help of Roush Racing, Ford Truck Public Affairs created a one-off Ford Ranger, dubbed the "SHO Ranger", with a {{cvt|2986|cc|L|1|order=flip}} SHO V6 and a Mustang GT's T-5 manual transmission. According to D.A. "Woody" Haines, assistant manager of that division, they commissioned the project truck "to test the market."<ref name="SHORanger">{{cite journal| last =Hamilton| first =Frank| title =SHO Down: Have you stomped in a Ford lately?| journal =[[Minitruckin']]| issue =Spring 1990| pages =28–31 }}</ref><ref name="SHORanger2">{{Cite web|url=http://rockledge.home.comcast.net/~rockledge/RangerPictureGallery/SHO/SHORanger.pdf|title=SHO Ranger article copy |url-status = dead | archiveurl = https://web.archive.org/web/20110723045856/http://rockledge.home.comcast.net/~rockledge/RangerPictureGallery/SHO/SHORanger.pdf | archivedate = 2011-07-23}}</ref><ref name="FordsSHORanger">{{cite journal| last =Cannell| first =Thom| title =One Quick Ranger| journal =Sport Truck| issue=September 1989| pages =56–61}}</ref><ref name="DrivingImpression">{{cite journal| last =Clor| first =John M.| title =Driving Impressions: Ford SHO Ranger| journal =Autoweek| issue=August 28 1989| pages =96}}</ref><ref name="PopularHotRod">{{cite journal| journal =Popular Hot Rod| title = It's Factory| issue =September 1989 | pages =62}}</ref>

In 1993, Ford Canada hand-built 40 Mercury Sables, some of which were powered by SHO V6 engines, as part of their AIV (Aluminum Intensive Vehicle) program and released 20 to the public. Using aluminum suspension elements and aluminum body panels, held together with spot welding and adhesive joining processes developed specifically for this vehicle, the end result was a car that was {{cvt|400|lb}} lighter than a SHO Taurus. [[Multimatic Motorsports]] entered one of these vehicles in the 1995 [[One Lap of America]] event, finishing 15th overall and 1st in the Mid-Price class.<ref name="SHOSable">{{Cite web|url=

== Modifications ==

A popular modification to cars equipped with the {{cvt|2986|cc|L|1|order=flip}} SHO engine is to replace the engine with a {{cvt|3191|cc|L|1|order=flip}} engine. Further modification can include installing the cams from a {{cvt|2986|cc|L|1|order=flip}} engine into a {{cvt|3191|cc|L|1|order=flip}} engine. These more aggressive cams, along with a higher torque output have been known to allow the manual transmission-equipped Taurus SHO to run into the low 14s on the {{cvt|1/4|mi|m|0}}.{{Citation needed|date=July 2010}}

== SHOGun Festiva ==
In 1990, Chuck Beck of Special Editions and Rick Titus took seven [[Ford Festiva]]s and mounted {{cvt|2986|cc|L|1|order=flip}} SHO V6s − still mated to their native transmissions − behind the front seats in [[MR layout|mid-rear engine configuration]]. Along with substantial cosmetic body changes, including custom fiberglass wheel arches to accommodate a wider stance and larger tires, the suspension was completely redesigned. Each car was painted a different color. These changes resulted in a car that could do a quarter-mile (400 m) run in 12.9 seconds at {{cvt|100.9|mph|km/h}}, and could achieve a lateral acceleration figure ranging from .95 to 1.04&nbsp;[[Gravitational acceleration|g]]. Two of the seven are notable; [[Jay Leno]] owns number 003 (the silver one), and number 005 (the purple one) included special modifications for competition in the [[SCCA]], including a rollcage and 5-point restraints.<ref name="SHOGun1">{{Cite web|url=http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=article&sid=231&mode=thread&order=0&thold=0 |title=Writeup on Jay Leno's SHOGun #003 |accessdate=2010-08-10 |url-status=dead |archiveurl=https://web.archive.org/web/20120204205920/http://www.shotimes.com/php-bin/modules.php?op=modload&name=News&file=article&sid=231&mode=thread&order=0&thold=0 |archivedate=February 4, 2012 }}</ref>
