History

The Shelby Cobra has gone down in history as one of the most iconic sports cars ever built. From the vision of Texan Carroll Shelby, the combination of a lightweight British sports car and a big American V8 made for a thrilling road car and super successful race car, winning multiple championships and races at some of the most famous tracks and events across the globe.   

This particular Cobra, COB 6033, is one of the most winning, and original competition Cobra's left. Built and shipped direct from the UK, it was campaigned with great success in Australia at a diverse range of events by first owner Ron Thorp. The COB designation in its chassis number, denotes it as one of the factory built RHD Cobra's, that used the famous small block Ford 289 engine that Shelby had hotrodded into the leaf sprung British chassis. These cars were built by AC under licence from Shelby American and had some subtle differences to the US Shelby Cobra, like the AC badge on the boot and a lack of "Powered by Ford" badges on the flanks. Engines and gearbox were shipped from the USA and fitted at the UK factory. With only 61 RHD AC Shelby Cobra's built they are a lot rarer than the 655 US LHD versions, and for some, (like RHD driving countires) more desirable.   

 

 

Our cars story begin when Ron Thorp called AC Cars, Thames Ditton, in mid 1964 to see about buying a Cobra as an upgrade to his DB3S Aston Martin race car. He had read many race magazine reports of the great success the Cobra's had in the USA and Europe, he liked British sports cars and thought it would be an ideal new racer for him. His sister was living in England and through her, he arranged a Vineyard Green MK2 Cobra with red interior (Despite factory records saying it had black, it was red and the only one ever built in this colour combination, which he requested as it matched the Aston Martin's colours) to be sent to Australia. It was also ordered with a matching green hardtop, so he could enter the car in a multitude of different race classes, putting the roof on to be an elligble for the GT class, then taking it off for any sports and racing car classes. Ron's sister visited the factory during different stages of its build, to take pictures of the cars progress to send back to an anxious and excited Ron in Australia. A couple of these shots can be seen below.

Being shown the 1501 miles already clocked into the speedo.

COB 6033's speedo was wound on to 1501 miles, to sell as used car and therefore lower the tax into Australia. It was also registered in the UK as DGJ 501B. It  was packed in a special wooden crate marked by AC cars "Cobra for Export" and shipped on 19th November, 1964 via 20th Century and Thomas Meadows, to Ron Thorp's Bargain Barn, his used car dealership in Wollongong, New South Wales. It finally hit Australian shores and picked up on Dec 24th 1964.

Ron said it was the best and biggest Christmas present he has ever opened.

 

 

Picked up at the wharf in Sydney, Dec 24th 1965.

 

 

Unpacking at home, a great Christmas present.

A lot of people commnet about the race number "69" we have on the car, which Ron plainly says he used as he only ever had to carry two numbers wherever he went. If it was not number "69" it was "96". But as you will see there are quite a few different numbers she ran in her 3 years of racing.

RACE HISTORY -1965

Jan 11th, practised at Oran Park where it was noticed the oil pressure would drop on any left hand corners.

 

 

First race meeting at Warwick Farm.

First raced at Sydney's Warwick Farm, Feb 14th 1965. Was fitted with a front mounted three point roll over hoop, and small Perspex windshield that was mainly to be used in Hillclimbs. The car was still basically a road car. Placed third in class (and 14th outright) after Thorp experienced oil surge and fuel starvation problems. He ordered a T pan sump and a new manifold with matching Holley carburettor from Shelby, which was fitted in late March and fixed the problems. Also received and fitted was an oil radiator. The Cobra was locally registered with the plate DPP 745.

June 7th Caversham 6 hour, 2nd to the 250 LM ferrari of Spencer Martin and David McKay. Although Ron entered the race with his wife Ann down as the co-driver, as required by the rules, but he drove the entire 6 hours solo, massive effort that he did each year he ran there. Caversham is in Western Australia, Ron and Ann would load the Cobra in his Austin 3 ton Cobra transporter (see picture below) and drive 4300 kilometres (2600 Miles) on mostly rough and unsealed roads ther and back for this race each year. It took the little truck, its passenger and the well shaken Thorp, one week to get there. then he drove the 6 hour, hopped in and drove it all back home.. Legend.

After reading Bill Carrol's book "Ford Cobra Guide",  that had an entire chapter on racing your Cobra, Thorp upgraded the car with an order from Shelby Automotive; He received and fitted, 4 x 48IDA Webers, with a matching Shelby manifold and a hoodscoop. More modifications were to come by the end of the racing year...

Nov 14th, Lakeside, DNS; Thorp travelled 1000km (620 Miles) North to Queensland for the Australian Tourist Trophy race, which was run at Lakeside International Raceway on Nov 14th. This was the event that Shelby sent over Ken Miles, Ron Butler and the factory 427 CSX 3002 to run in the race.

 

 

Rare colour shot from practise at Lakeside, passing the 356 Carrera of Tony Basile.

Thorp, who was very keen to race against the "works" Cobra, ran into trouble with some over zealous scrutineers who picked up that his wheels were ¼ of an inch proud of the guards. They offered Thorpe a solution of taping some wooden coat hangers to extend the guards. But Thorp gave them his thoughts on it and then went out and qualified the car. In the first race he was waiting on the starting grid when the chief scrutineer approached him and said it was ok for him to race with the guards as they were, but he would not be listed in the official results. He told them told them to shove it, drove off the grid, packed up the car and watched the race instead. He never raced at Lakeside Raceway again. this was the only tme that two Shelby Cobra's were on a track in Australia together.

Dec 5th, Warwick Farm, 3rd in Production Sports class.

Thorp won the 1965 Australian Hillclimb Championship for Production Sports Cars (The championship was a series of seven hillclimbs, Thorp missed the first one in January at Amaroo NSW as the car was not ready, but he competed in the remaining six events.)  

 

 

December 1965 and the Cobra's guards were modified to fit the bigger Halibrand wheels.    

At the end of the season the final run of modifications were made to the Cobra, a set of magnesium Hailbrand wheels from Shelby were fitted as well as Derrington racing headers and side exhausts. Wider guards were also fabricated to fit the new wheels. He had a special lightweight perspex fairing made for hillclimbs and some circuit races to replace the heavy windscreen. Just before the 1966 Cavesham 6 hour race, new big brake scoops were made for the front and rear brakes.

POST RACE HISTORY

After having raced the car for almost every 2nd weekend, 3 years in a row, Ron was ready for a break and parked the Cobra in his shed in 1968. It was still used  occasionally, but only on the road. He then pursued his new love of planes and flying. It is of credit to Thorp, that in all the time he raced the Cobra, he never once marked it.

 

 

The Thorp barn, a young fan visited Ron and was lucky enough to get a ride in the early 70's.- Pic from "lucky" Phil Hall.

Geoff Dowdle was a young and avid car fanatic with a  particular passion for Cobra', after seeing Ron's car race at a few local hillclimbs. He was looking to buy another Cobra and heard that Ron still owned and had the car in Wollongong.  He located and approached Ron about buying the car, who declined his initial inquiry about purchasing it, but a year or so later he rang Dowdle back to see if he still wanted the car. 

Dowdle had to sell his Austin Healy and Jaguar E type to raise the $6000.00 Thorp was asking. He did so and became the Cobra's new owner on the 12th of May, 1973, with 11 800 miles on the clock. Dowdle resprayed the car, keeping the original colour and retained the original interior. He left all the racing equipment on it and became well known in his local area through the car being such a noisy thing with the racing side pipe exhausts!

After many years of happy ownership, COB 6033 was sold to John Blandon, of South Australia in August 1980 for $42 000.00.

Entered by Blandon in numerous historical events including the Australian GP historic sports car races and the Classic Adelaide Rally. It was also featured in the books "Bathurst, the cradle of Australian Motorsport", "Ford Australia, The Racing History" and Blandon's own big book that documented many of the great race cars that had lived in Australia, aptly named "Historic Racing Cars in Australia". 

 

 

  The Cobra while in John Blandon's custodianship.

Blandon, who was a bloody good bloke and was a large influence on the Australian motorsport scene, unfortunately passed away before his time in April 2004. The car was put up for auction, along with other cars from John's impressive collection at the first Bonhams auction in Sydney, May 2004. His 1977 Moffat Dealer Falcon Hardtop #2 and COB6033 were sold to David Bowden. We are pretty sure John would be happy that both cars went to a good home and are still very much loved.

COB6033 still has all its original racing components, original red interior, has now done just on 30,000 miles (minus the 1500 "done" in the UK). The factory hardtop, whilst a bit rough, still has the original vineyard green paint (and came up nicely with some of our Auto Body Cleanser and then wax).

 

 

Ron Thorp visiting his famous car in 2005.

First Owner Ron Thorp and his son, Ron Warwick Thorp, also visited in 2005, both happy that the Cobra is being looked after and amongst good company. Ron bought along two huge scrap books with all the details of every race and event the car entered. The sheer volume of information they have of the cars period race history is amazing, from reports of every race (and the images shared in this article here) to lap reports, money spent on the car, even arm bands and tickets from the multitude of races they attended. We have never seen anything like this scrap book, It is a great testament to the Thorp family's love of the the little Cobra. 

Second owner Geoff Dowdle visited Bowden a little bit later and gave him the original registration plate from England, DGJ 501B, which now proudly sits on the cars rump. It has been more recently featured in numerous Australian magazines including Unique Cars, Australian Classic Car and Australian Muscle Car.

GOODWOOD REVIVAL 2012

 

 

In early 2012 we were a bit delighted to get a letter rom Lord March with an invite to run the Cobra, in a special all competition Cobra race they had planned called the Shelby Cup. It was 50 years since the Cobra came into being, when Carroll Shelby mated the AC body with the Ford V8 engine an created an all time sports car classic, so this one off special 50 year anniversary event was well worth attending and sending COB6033 back over the pond for. Its first trip back to the homeland since arriving in 1964... To make it even more special we had Ron Thorp join us for the trip.

 

 

This is a field, all genuine period race Cobra's.

 

 

Chris Bowden having a pretty good day in the Cobra.

Read and see all about our big Goodwood trip, and the race with 33 other Cobra's at the Goodwood revival article here.

COB 6033 now spends its day's getting pampered in our sheds, with the ocassional spirited run through the hinterland and the odd car show and event. It is one of the favourite cars in the collection, being magnificent to drive, having all the right sounds, elligible for just about any car event you would like to do and best of all, she blows flames on the over-run! In fact, we say if there was just one car you could have and die a happy man.. I think this would be it.. Big call when you look what is in our sheds, but it is something that all previous owners have said, including ourselves.
