This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 3.85.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 21:48, 22 February 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''Ford Super Duty''' engine is a range of [[V8 engine]]s that were manufactured by [[Ford Motor Company]].  Introduced in 1958, the Super Duty engines replaced the [[Lincoln Y-block V8 engine|Lincoln Y-block V8]] (alongside the smaller [[Ford MEL engine|Ford MEL V8 engines]]). 

By the end of the 1970s, the use of the Super Duty engine began to decline in heavy trucks in favor of diesel-fueled engines; in medium-duty trucks, variants of the similar-displacement (but higher-efficiency) [[Ford 385 engine|385-series]] V8s became more commonly used. In 1981, Ford withdrew the Super Duty engine line.

Through its production, the Super Duty engines were assembled by Ford in its [[Cleveland Engine|Cleveland Engine Plant #2]] in [[Brook Park, Ohio]].<ref>((citation|title=History of Cleveland Manufacturing Plant|date=Nov 5, 2004|publisher=Ford Motor Co. via Allfordmustangs.com|url=http://www.allfordmustangs.com/articles/history-of-cleveland-manufacturing-plant-466.shtml|accessdate=2018-09-08))</ref>  

==Design==
The Super Duty engine is 90-degree overhead-valve V8 with angled piston decks. The cylinder heads are flat and the pistons are crowned to create a wedge-shaped [[combustion chamber]] within the cylinder bore; the compression ratio is 7.5:1 for all models. They are typically governed to 3400 rpm.

Three displacements were available during production: ((convert|401|cuin|L|1|abbr=on)), ((convert|477|cuin|L|1|abbr=on)) and ((convert|534|cuin|L|1|abbr=on)); but however large, the 534 was very much smaller than the ((convert|1100|cuin|L|1|adj=on)) [[Ford GAA]] all aluminum 32 valve [[DOHC]] V8 (introduced during WW2), which was the largest displacement gasoline engine ever mass-produced by Ford Motor Company for use in land vehicles.

The 401 has a cylinder bore and a stroke of ((convert|4+1/8|x|3+3/4|in|mm|1|abbr=on)). The 477 shares the 401's stroke with a larger ((convert|4+1/2|in|mm|1|abbr=on)) bore; the 534 has this same bore with a stroke of ((convert|4.2|in|mm|1|abbr=on)).

The early Super Duty has a unique intake system where the intake plenum is connected directly to the cylinder head; all four cylinders pull the air/fuel mixture from a single "log" type port in the head. The engines could "spit" when cold and blow the choke plate out into the [[air cleaner]] because of the large port configuration. In later engines this was corrected with a conventional spider-type intake. The [[exhaust valve]]s are filled with [[sodium]] to carry heat from the valve head to the valve spring, which would dissipate it into the oil coming off the [[rocker arm]]. (It is more likely that the sodium in the valve stems in these engines carried the heat to the coolant in the cylinder head, not to the valve springs.)

A marine version of the 534, the "Seamaster", was available from the Seamaster Marine Engine Co. starting in the late 1950s. It was available either [[naturally aspirated]] or with [[twin-turbo]]chargers with an intercooler, and had a dry weight of over ((convert|1300|lb|kg|abbr=on)).<ref>((cite web |url=https://hooniverse.com/534ci-twin-turbo-super-seamaster-is-here-to-shame-your-gm-twin-six/ |title=534ci Twin-Turbo Super Seamaster is Here to Shame Your GM Twin-Six |publisher=Hooniverse |accessdate=11 January 2024))</ref><ref>((cite web |title=Another Forgotten Ford Big Block: The Giant 534 SD V8 |url=https://www.macsmotorcitygarage.com/another-forgotten-ford-big-block-the-giant-534-sd-v8/ |website=Motor City Garage |access-date=12 January 2024))</ref>

== Applications ==
Among the heaviest and highest-displacement V8 engines ever built by Ford, the Super Duty engines were never used in automobiles; its debut in medium and heavy trucks marked the renaming of Ford F-Series "Big Job" conventionals after the engine. Slotted above the 330, 361, and 391 [[Ford FE engine|FT]] V8s used in the medium-duty F-Series (F-500 to F-700 and B-series), the Super Duty was used in heavy-duty trucks, including the F-800, F-900 "Super Duty" conventionals.

Outside of the F-Series, the Super Duty engine was used in several model ranges of Ford heavy trucks, including:

* [[Ford C series|Ford C-Series]] low-cab COE
* Ford N-Series short-hood Class 8 conventional (replacement for F-Series conventional)
* Ford H-Series (Class 8 COE; "Two Story Falcon" variant of C-Series)
* [[Ford L series|Ford L-Series]] (Class 7-8 conventional)
