eeek.... thats really scary to see how inccurate prints can be 8o
...gotta trace some accurate Cobra prints from 3D model @ someday.
We have tonnes of 427 Shelby Cobra Blueprints on this site, I'd like to see some 289FIA blueprints.
Well, there may be plans of "other" cobras, but isn't this one above meant to be the first prototype?
The petrol cap in the middle of the rear deck.......didn't all production models have it to one side, or is that a myth?
You think they are innaccurate? I think you might be looking at the plans for the very first car that came to America, that Shelby and Moon fitted a 260 Ford Fairlane motor into... (Shelby'd already helped AC fit a 221 version in Britain, but with the 260 coming into production, they shipped the first rolling chassis to America without the motor.) and then went out looking for Corvettes to humiliate.
If you read the text in the images, that seems to be what they are saying.
Is there some all knowing cobra maniac that can throw any light on this?
Hey seasalt, there is another cobra blueprint (in fact there is a number of them) in the shelby section if you want to analyze that one as well!! Just Kidding.
I think that is just a really inaccurate blueprint, or possibly someone's interpretation of a cobra.
As for the fuel cap, 289 FIA (thats the race 289 model) had it mounted on the rear deck, off center towards the right rear fender. It was the Le Mans type fuel cap, (from an aston martin I think?) spring loaded, flip top, Clip down. 289 Slabside (aka street, called slabside because of the flat sided wheel arches) had a smaller (different shaped) cap, and it was mounted in 427 position (on the right rear fender) BUT, looking at some pictures it appears that they may have had it mounted in the center of the rear deck (i think this may be british models only, USA models had it on the fender)
AND we all know the 427 had the Large Le Mans, Spring Loaded, Flip top, Clip down, fuel cap on the RIGHT rear fender.
yeah, bit carried away there.
Walkden Fisher was a real draftsman, and lots of his plans are at http://www.vsrnonline.com/SearchIndex_3Views.html l
where plans are available for modellers. So he's not some kid with photoshop.......tho its probly not a proto....thats the magazine name...."prototype parade"...its scanned from.
The 260ci Mk 1 cars all went to America, and weren't sold in Britain until the '64 Mk2 289 model. If this is how the British market version looked, then are there other parts that qualify it as a "bad drawing"?
The text accompanying the plans above reads:
A. C. Cobra DRAWN BY WALKDEN FISHER
A name and a car that has become increasingly well known on European racing circuits during 1964 is the A.C. Cobra the sports version of which is a truly hairy machine, and a delight to the countless enthusiasts who can recall the big, powerful spectacular vehicles that proved such great spectator appeal some years ago.
On British circuits the Willment A.C. Cobras have become familiar sights that have added considerably In the interest in sports car events. With their raucous exhaust note and eye catching colour scheme of brilliant red, superimposed with white bands, these husky machines have proved themselves to be a definite threat in every race.
Earlier this year at Sebring Cobras created a great impression by winning the G.T. class, and but for sheer bad luck they might well have been the overall winners. A class win in the Nurburgring 1000 kilometres race by a Cobra driven by Jo Schlesser and Richard Attwood added to the growing reputation of these Anglo American machines, and in the 1964 Le Mans 24 hour race a G.T. Cobra finished fourth overall. This car. driven by Dan Gurney and R. Bondurant won the coveted Grand Touring Trophy and thus deprived the Maranello Prancing Horse of an award that is much sought after, and one that carries with it a great deal of prestige in the motoring world.
Much of the credit for fitting large American engines in modern lightweight European production sports chassis lies with Carroll Shelby, who teamed with Roy Salvadori in 1959, and won the Le Mans event. Well known in racing circles on both sides of the Atlantic Shelby, retired from the sport of road racing at the height of his career. and concentrated on a project of his own a desire to produce the fastest production sports car in the world. It was late in the year of his retirement, 1961. that he heard of the impending winding up of the A.C. works in Britain producers of the A.C. Bristol sports cars. Following negotiations with Ford and with the A.C. concern, Shelby succeeded in gaining the co operation of both, the latter company agreeing to continue producing bodies which he proposed to mate with the potent Ford Fairlane engine. This necessitated a number of modifications, which included the strengthening of the chassis to bear the larger power unit; the Fairlane being about 2 times the size of the Bristol engine that had powered the car before. The body itself was lengthened and eventually the A.C. Cobra came into being.
Construction was carried out, in Britain, and when the prototype was later taken to the United States the Ford engineers gave it a thorough test and found it to be sound, the only change they recommended being the fitting of American electrical components to assure that replacements would be readily available in the States.
Victories in American events followed, and the car soon began to prove itself as popular on the street as it was successful on the track, although Shelby continued to maintain that he was interested only in limited production, so that the A.C. Cobra could be sold only to the "true enthusiast".
The sports Cobra has a general overall appearance of huskiness, emphasised by its big wheels, and its potent aspect is substantiated by terrific acceleration and leech like road holding the standard car will cover the standing quarter mile in about 13 seconds and attain a maximum speed of 135 m.p.h.
Under the bonnet is housed the 300 bhp., 4.7 litre Ford V8 model 289 engine; the power of which is transmitted through a Ford all synchromesh gear box. Independent front and rear suspension is by transverse leaf spring, wishbones and telescopic dampers. Girling disc brakes are fitted all round, and the body shell is all aluminium, hand formed at the British A.C. Carriage Works.
