I am selling this car for a friend. I have been involved with classic automobiles for almost 40 years. I have built and restored many Corvettes and Porsches and am a member of numerous car clubs including PCA & NCRS. I have judged at many concour events in and around Southern CA. This is a stellar. turn-key automobile at the highest-level of restoration. I hesitate to call the car concour because it is driven. but it is indeed very close. An undercarriage detail (it's very clean. but not detailed to perfection) would be required to make concour. I would call this car a #1- based on everything that I see. The body & paint as well as interior and engine bay are all in #1 condition.
This Arntz Cobra is an exact “replica” of a 1964-65 Shelby Cobra was built by the legendary Steve Arntz in 1978 and from 2002-2008 was completely restored and further modified to near perfection. Arntz from South San Francisco worked with Carroll Shelby on the original Cobras and went on to be the first builder of Cobra replicas. His cars were built with incredible attention to detail. significant improvements to the Cobras. especially in the area of performance and safety. He designed his cars as turn key examples for possible sales to Ford Motor Co. but were never put into Ford's production line. All his cars were built with Ford or Chevrolet engines during his production run. Later the company was sold to a former crew chief for the Shelby Racing Team. Ron Butler.
This quality of this build and the amazing handling capabilities of this vehicle will surpass any original factory Cobra or aftermarket kit car available today. It is the strongest. sturdiest and heaviest frame of any Cobra ever made. and with the Jaguar XKE center section. this car is capable of withstanding incredible torque output from modern aluminum Chevrolet power plants as used in McLaren Can-Am race cars.
An original 427 Cobra today is in the $1. 2M range and is an amazing collectable no doubt. but here we have a substantially better machine at less than 1/10th the price. Arntz Cobra's are extremely rare. with a number less than 100 (from my research 65 were made) ever built by the Arntz/Butler factory team as replicas. I want to emphasis. this was not a kit car. This car was similar to what Ford did in the 2005-2006 Ford GT's. These were a replica in modern standard formulation to emulate the original Ford GT's. Arntz was essentially doing the same thing with his Cobra “Replicas”. These were not some car pieced together by some guy in his garage. The restoration process to this particular vehicle was done to concour quality standards with many modifications to make it even more desirable than it was when originally built by Arntz.
I cannot emphasis this enough. you are not looking at some pieced together kit Cobra. this is the real deal built by two guys that worked hand and hand with Carroll Shelby. building race-cars. These guys were engineers of the highest order. If you live in Southern California or have the ability to fly in and look at this elaborate piece of automotive history please try to come check it out. The sight. the sound and the driving experience is like no other Cobra I have ever witnessed. The handling capabilities are simply superb. The “stout” frame gives the car a definitive feeling of confidence. Please take the time to read the specifications built into the Arntz Cobra.
About Steve Arntz & His Cars
A bit of Steve Arntz information and history: Steve Arntz worked with Carrol Shelby on the original Cobra's and after that project ended he continued and was the first man to build a Cobra replica. Steve Arntz started the kit Cobra industry. enabling so many to own their dream car.
Here are some comments of what others say about the man and the cars he built.
"This all started with the first clone Steve Arntz body…”
"Virtually all the Cobra Replica manufacturers that came in the years after us bought cars and chassis from us - ALL. "
"Produced by Steve Arntz in the late-70s. this American made Cobra reproduction is as rare as it is stunning. Arntz was a pioneer in the concept of reproducing Shelby Cobras & this vehicle is testament to the quality of his workmanship. These cars are not the same as the kit cars that are being sold today. There were very few of these cars built and even fewer on the road today. "
"Steve Arntz started building replica cars in 1972 in South San Francisco. Steve is and always will be an R&D man. He'd build a car. drive it for an hour. and then tear it apart again. This went on consistently. By the time I met him in about 1989. he had a shop at Sears Point. The one thing that everybody agrees on. is that Steve was light years ahead of any other replica builders. He never sacrificed quality for price. If you could see a Arntz car. next to pretty much any other manufacturer. you would see the difference in quality and safety features. many of which are incorporated in other cars today. "
“The Arntz Cobra has a unique steel structure that separates it from all other Cobra replicas. One of these features is the steel door beams and hinge designs that are fiber glassed into the doors during construction. There were dozens of jig fixtures that were included with the tooling and fixturing of the body mold "package" that insured the proper location of all these components. You might have a similar "body" mold (the body is easy enough to splash). but without all the other components and the knowledge that it takes to put it all together in order to duplicate the Arntz design. you don't have anything any better than 90% of the rest of the wannabe's out there. These were some of the primary things that made (makes) the Arntz so different and so much better that most (if not all) others. Giving credit where credit is due. the Arntz was originally designed to be a Cobra that one could drive every day. as a daily driver. I saw a demo that Steve Arntz had which had well over 100K mi. on it. It was in better condition than a lot of production cars of today. ”
“What most people don't realize is that the Arntz Cobra. back in the 70's-80's. was a FULLY engineered car. When he went to Ford. there was a manufacturing blueprint drawing for every single part on that car. Hundreds of the best quality (back then hand drafted) drawings and spec sheets you could imagine. I saw them. There isn't another replica out there which can match it's quality and engineering. even to this day. AFAIC. I was willing to put my name and stake my reputation on it.
The Shelby Cobra was so successful that once production ended in 1967. it became the car that spawned the most replicas ever in the world! Steve Arntz was among the first to start producing a roadster in 1976 that replicated the Cobra 427 S/C. Consisting of a square tube frame and a fiberglass body whose molds were formed from an original model from 1965. and thus offering an almost perfect likeness. the car we offer is equipped with a Chevrolet 406 cu in V8 with whose tuning. according to the previous owner's information. is good for 512 hp. with an Edelbock intake manifold & Speed 750 Demon carburetor. The engine is mated to a Muncie 4-speed “Rock Crusher” and the car features independent Jaguar rear suspension. plus four disc brakes. The interior displays beautiful Auto Meter instrumentation. and G-Force harnesses. Many of the detail accessories are from Shelby American. which gives the car a certain flavor of authenticity. Only 65 units were produced between 1976 and 1981. This car has incredible performance and offering dragster acceleration! The ideal car for seekers of sustained excitement.

The 406 small-block engine in this beast is the perfect blend of power and torque fitted to a lightweight racing specimen. The power is incredible. the sound is intoxicating and the ride quality and safety features of this machine are about as good as it gets. This is about as much fun as you can have with an automobile.
This little gemwas meticulously restored over about a seven to eight year period as far as I can tell from all the receipts that come with the car. The receipts total over $56K since 2002. However. there are a lot of things that are not found in the receipts. For example the ET Racing Wheels are somewhere in the $800 each category. My personal opinion is there is probably closer to $75K in the car to get it to its current restored show quality condition. Most everything was done by professional shops dedicated to racing type of cars. The car has been meticulously cared for and has less than 12K miles
on the odometer.
Paint & Body
The color is a Dodge Viper Graphite Metallic on the Hood/Truck Stripe and the body color is a 50% reduction of the same color. The most interesting thing to me was how many different shades it takes on during the day. depending on how much light is directly or indirectly on it. The beach pictures were taken on a very blue-sky morning and the color takes on that blueish hue. It's one of the most striking colors I have ever photographed on a car and is just stunning when viewed in person. It's a very similar color to the 2005 Ford GT Tungsten Gray Metallic; albeit more vibrant. The picture with the people gathered around the car at the Sacramento Autorama seems to capture the truest color of the car to my eye.
Make sure you check out the pictures showing the hood and trunk (in open position) stripes as they are “flip-flop” painted on the inside to match the outside. It's a total WOW. I cannot stress enough the quality of this paint job. The current owner was a painter for many years in a very high-end shop in Southern California and he is most impressed with the body and paint. If this Cobra was rolled onto the lawn at Pebble Beach. there would be a crowd around it all day. It's just that nice.
Engineering the Arntz Cobra (from Hot Rod Magazine June 1980 Issue)
As good-looking and as quick as the Arntz Cobra is. the thing Steve Arntz is proudest about is its engineering; and he would rather talk about the strength of the doors than discuss how faithfully the body resembles the original 427 Cobra. Steve set out to make his car better than the original (having owned several AC Cobras. he was well acquainted with the car's shortcomings) in terms of safety. reliability. handling. passenger comfort and performance.
As an example of the improvements made. the original Cobra was nose-heavy. which caused excessive rear wheel spin during hard acceleration and rear wheel lockup under braking. Steve moved the engine back (10 inches). which improved weight transfer during acceleration. and gave more rear wheel weight (negative weight shift to the front) during braking. Both features improve handling and acceleration.
The frame was designed to be more than twice as strong as the original. and the Arntz Cobra can handle the most powerful of today's high-performance street or racing engines. The rear fender-well design allow 50 percent wider tires than could be fitted to the original Cobra. This means improved traction and smoother ride.
No one know the Arntz Cobra better than its designer. so we asked Steve to expound on the features of the car.
FRAME - “After considerable discussion about what the frame should actually be. we arrived at a parallel ladder design that incorporates 3 X 4-inch steel members of 1/8-inch-wall material comparable to a 1018 SAE grade steel. The perimeter frame rails are 4 X 1. 5-inch 1/8-inch-wall steel. These surround the entire perimeter of the passenger compartment. providing not only substantial frame rigidity but some additional safety features as well. The torsional rigidity theses rails create translates into improved chassis stiffness for better braking and cornering.
The X-bracing portion of the frame is constructed of 4 X 1. 5-inch box steel tubing laid out to accommodate standard-shift 4-speed and Doug Nash 5-speed transmissions. as well as an assortment of automatic gearboxes.
Other features. such as solid=mounting the Jaguar rear suspension member. add to the net chassis stiffness. The design of a frame that meets our standards is a blend of handling and safety features. If a particular chassis feature looks good but doesn't contribute to safety or performance. we omit it. The Arntz Cobra is intended as a pure automotive design. not simply something meant to sell.
The addition of strengthening gussets and fish plates brings the total weight of out frame to about 240 pounds. Considering the design strength of the frame. it's very lightweight. Part of this results from use of single-bead. hili-arc. aircraft-quality welds throughout the entire frame. ”
BODY- “The body is an exact reproduction of a 1967 427 Cobra shape. and we'd like to emphasize “shape”. Structurally. we've designed a fiberglass body of superior durability compared to the original aluminum skin. Our body thickness varies from 3/16- to 1/4-inch. Bodies are permanently bonded to the inner panels. which are also constructed of similar thickness fiberglass.
All the original Cobra external feature integrity is preserved in the Arntz version by offering exact reproductions of the windshield frame and glass. front and rear bumpers. front and rear lighting fixtures. rear-view mirrors and comparable pieces. In fact. we have been able to locate and contract most of the original vendors for AC Cobra accessory parts and offer this for of authenticity with the Arntz package.
Each body door has a steel guard rail constructed of 2 X 4-inch 1/8-inch wall mild steel tubing connected to hinges that have been pressure-formed in a huge press. These guard beams and hinges are of sufficient strength that the entire car can be jacked off the ground simply by placing the jacking member beneath the guard beam of the door. which will support the entire raised vehicle weight.
Inside the driver/passenger compartment. we have given considerable design thought to the dimensioning of foot boxes. arm leg and hip room. so that both persons are functionally comfortable and have optimum road visibility.
Our brake and clutch pedal assembly operated on roller bearings with a single hydraulic slave cylinder for clutch actuation and two independent hydraulic cylinders for the brakes. This special-design assembly is also adjustable forward and rearward to accommodate variation in driver leg length. A race-car brake balance bar is also included for front-to-rear brake pressure proportioning.
Arntz Cobras have four-wheel disc brakes. This includes the stock inboard-located Jaguar rear disc brakes. In the front. we provide a special Huffaker/Arntz design of superior street capability and worthy of race-car use. (Joe Huffaker's association with the Arntz Cobra is only one of several -including that of master race-car fabricator Ron Butler-that have arisen from the interest among true automotive professionals who recognize the potential of the Arntz Cobra. )”
SAFTETY. DESIGN & PERFORMANCE “Our steering system is rack and pinion. the same design used on the original 427 Cobras. Perhaps the best available anywhere. it adds to the precise control required of any high-performance vehicle.
Working in conjunction with Koni shock absorber engineers. we have developed a unit that is tailored specifically to the Arntz Cobra.
Race-prepared rear suspension “center sections” are available from Arntz Engineering.
Regardless of the type of engine and exhaust system selected. we provide a special heat shield located between the exhaust manifold on the driver's side and the outside of the driver's foot box. Not in contact with the foot box or manifold. this shield provides adequate temperature control during times when air flow through the engine compartment is low.
This proximity of engine to firewall and foot boxes is the result of having moved the engine 10 inches rearward from where it was positioned in the original Cobras. Where the AC Cobra had about 53 percent of its weight on the front end. we've been able to redistribute this so that 56 percent of the total vehicle weight is now on the rear end. Given sufficient tire width and traction. lateral G-forces in excess of 1. 5 are easily accomplished.
We also build and offer a 4-inch-thick-core. special-design radiator that will accept the cooling requirements of just about any engine our customers might choose to install.
Fuel is carried in a foam-filled. ballistic nylon fuel cell that mounts just behind the driver/passenger compartment. Capacity is rated at 16 U. S gallons. Because of the design of this cell and its location in there car. there are no space sacrifices. There is sufficient trunk space for three standard-sized suitcases. ”
To sum up its builders words: in our opinion. the Arntz Cobra is more than just another pretty face-it is a totally engineered car backed by a real commitment to quality.
This rare and unusual Arntz Cobra has got to be one of the most complete and gorgeous examples in the Country. These cars are bona fide rarities and only occasionally come up for sale.
Cobra. For millions of people in the world. just five letters from the alphabet. For some. however. it is the five letter code for a phenomenon that defies technical description. To put it another way: for them. it is the legend of the Shelby Cobra.
