427 cui in a Mustang have always been magic digits for  Mustang Enthusiasts, but only a few have the opportunity to experience the extra punch of a true racing engine. You  missed something,  that is for sure.	The above emblem is attached on a mystery 1968 Fastback. It is similar to a 427 Cobra emblem. I had the pleasure to be a passenger once in Switzerland and enjoyed the rough ride. The car had been sold soon after and the current owner wants that car to remain uncovered and unpublished.  We  respect his desire.

This site is an attempt to collect more in-depth info on this special breed. Thanks to some enthusiasts out there in cyberspace, there is already a bunch of information available. Still a 427 Mustang has always been one of my dreams. I had the opportunity to buy one a few years ago and had a thrilling test ride in it. 

But I could not afford it at that time actually. Yet it left a deep impression and I regretted it already a few years later.

I think from memory the first 427 Hi-Riser campaigned in a Mustang was the one by Hawkinson Ford in 1965 driven by Ron Pellegrini starting off with a 130mph/10.91 ET. Pellegrini later succeeded to drive the further developped and then called Super Mustang with an ET of 8.82 and 173 mph.

Several AF/X Mustangs were reunited during the Ford 100th. Steve la Riviere from Mustangs & More pictured them in his online photoalbum from the Anniversary and gave permission to use them once. You may wish to browse their famous Mustang site for more pics of the 427 Mustang strippers from 1965/66 that were on display. 
Gas Ronda, Dyno Don Nicholson, Bill Lawton, Bob Taylor, Malcom Montgomery and many more are famous names of racers, that had their share of extra 427 fun back then.

More pics see www.mustangsandmore.com

In 1966 the strippers got an extended nose for a more stable nose-down launch.
Still the 427 were the engine of choice. Picture: Ford

A 1967 Shelby G.T.500 with a 427 Tunnel Port Engine.
JBA Racing once was campaigning this car featuring a unique set-up, a 427 Tunnel Port engine. 500 HP really made a difference on the track.

JBA 427 tunnel port racing engine. It is backed up by Doug Nash 5-speed, naturally aspirated by a 1050 Dominator 4V carb, but takes a dose of NOS, if needed. Stepped custom headers by JBA, TA Magnesium Torque, Thrust D Cheater 9" wheels. and a Detroit Locker 31 spline 3.00:1 rear axis - J&V. Bittle from San Diego/CA know their stuff.

Dealers like Robie Ford or Foulger Ford advertised 427 conversions. We can only assume how many customers chose the option or just bought a unit to have it installed later.

The early years saw  lot of 427 (even SOHCs) ending up in drag cars. This one is from Hansen Racing in Sweden. The engine was much later sold and ended up in a mates 68 Mustang street car in Norway.


Here is a 427 from down under that show signs of a Holman Moody connection. Looks like a real performance car.

....there are many 427  Mustangs out there, built by true Mustang maniacs, which might be added later.

Cory Ellwyns 1968 black-gold 427 Mustang is a stunning example of what you can do with the right ambition. A 427 4V MR big block with custom made Ross pistons and ,Comp Cams valve train went in. Of course fully balanced. Still one of my favourite. For more info on this one check out this Special

Recent updates:
We will also show another 1967 Shelby with a 427 side-oiler soon.

A 427 Mustang stroked to 455 exists in Norway. Trond P. was the owner, who had this one on sale around 2016/2017.

The Mystery 427 Mustangs
Those following Ponysite.de for a longer time, know that we - in cooperation with Ford Enthusiasts around the world - have a tendency to unearth rare or never seen pictures, documents and such on various topics in the Mustang or Ford world.
Here are some  put together, where we've received information in the mail. 
Whereever you have more information, pls. contact us immediately.

The planned and already published 427 W-code engine that was supposed to go into the 1968 Mustang, but actually did not on the Ford assembly line. The reason for pulling the plug on this engine in a Mustang were simply costs. The 428CJ turned out to be much cheaper. 
Still the W-code was published in the Shoptip in1967 announcing the new model and in the Shop manuals for 1968. They promised 390HP/5600rpm and 460 lb/ft of torque at 3200rpm.  Compression ratio 10,9:1.
Kevin Marti repeatedly confirmed that there was definitely no W-code 68 in his files, so don't ask again. There was none ex-factory officially.

Probably the only official picture of a 1968 Pilot Mustang with a 427 engine, probably an original S-code. Courtesy Fordflashback.com. A former Ford studio employee confirmed to us that quite often these experiments were done and that he could not think of the unlogical thing, that a 427 was not put in a Mustang just for the testing. He is quite sure, it was done, but cannot actually proof it with documents. We later found thanks to a former Ford employee official Passino papers indicating that indeed 2 1967 Mustang got an 427 enging installed for testing.


This 1968 Mustang had a 427 engine built in and was campaigned by Tasca with Bill Lawton at dragstrips. Tasca merchandised a King of the Road package in this combination.

Communication is around with HM that maybe 10 were built by HM on request by several customers.
One name is known at least (Mr. Zxxx). But none of the cars that were claimed as the real deal ...was confirmed as far as we know. 
A guy "Joe" turned up to have a 68 with modified shock towers and a roll cage and it sounded like it is a real car (acc. to  Lee Holmann), but we have not heard anything  about this car since 1999.

This is a 1967 Shelby, where the owner claims that it has a Holman-Moody prepared 427 engine. That might be true, but it is not the original engine, as we found out with more research. 
The original engine blew in 1970 acc. to SAAC-records and reported by the original owner long time ago.

Still it is a stunning 427-Shelby combination and its value gained, if the HM-source is documented.

Aside from the only Super Snake 1967 Shelby (700HP High-Riser 427), that everyone meanwhile should know probably 47 427 Medium Riser 1967 Shelbys were built by dealers as the saying is, around 25 alone maybe by Tasca. 

One of those with a documented history and a correctly time-dated 66 427 side-oiler engine was recently featured in the Muscle Car Review magazine in Winter 2006. Price tag around 7500 Dollar, featuring 600HP.
Owner: Mike Stickney, restored by Rick Parker.

The saying is that Holman-Moody prepared also four 1968 Mustang Coupes with an 427 engine for racing. It was stated by Lee Holman at the Le Mans Classic 2006, that they were sent to Henri Chemin of Ford France. One is very well known having been raced by him.

Another or the same having been raced by Mr. Moga in France.
The third one ended probably up in Martin Birranes hands in UK. The car was advertised later and sold after 1970, but reportedly later crashed and is gone forever.

Watch out for the remaining ones.

Rumour:
The saying is that one of the original Le Mans GT40 427 engines disappeared from one GT40 after the race in 1967 and was built into a Mustang by a son of a Ford Representative. We have yet to find any proof for this.

A friend of mine owns this 1967 equipped with a 427. The ultimate sleeper.
