Cobra and GT40

Authentic components for a period-correct replica ...or a 100-point restoration.

Over the years, I've restored countless Weber carburetion systems, many of which were on original Cobras and race cars. In the old days, I even tweaked the Webers on two of the original Cobra Daytona Coupes.

Rebuilding so many of those original carburetion units gave me an opportunity to see how they really came from the factory. The funny thing was that at the time, I never thought too much about it. Being around those cars and tuning their carburetion was simply "what I did". It proved to be a valuable history lesson, because now, authenticity is important to many customers.

The Weber-carbureted Cobras, Daytona Coupes, and GT40's had some special components. Today, with the advent of the replica car business, there is a renewed demand for some of these parts, which I now manufacture.

I'm very proud to be the only supplier of the unique pieces that became obsolete over the years. These are exact reproductions of the original parts and components that these Weber carbureted cars used, just as they were, exactly as the factory (or Ford dealers) offered them.

Shown below are some of the special components that will make your restoration or period-correct replica more accurate.

Original-style 289 Cobra Roadster unit

Cobra Induction

COBRA-lettered intake manifold with center shaft linkage, separate front waterneck, and early style fuel harness identify this as a replica unit for a 60's-era Cobra. Remote thermostat housing is also included. Height as shown: 10-3/4"; add 1/2" if using individual velocity stack filters. This unit can be lowered to 9-5/8" for Daytona Coupes,with an extra charge for the specially made velocity stacks and custom machining of the booster venturies to shorten them to match the shorter velocity stacks.

The replica COBRA units are available in 2 styles: opposed or non-opposed carburetor layout. Many of the Cobra factory race cars had "opposed" carburetors (arranged back-to-back). Others were equipped with non-opposed manifolds, so either is correct. Non-opposed manifolds appeared on the following Cobra race cars: CSX2385; Ken Miles' CSX2431 #98; factory team car CSX 2121; and the 1964 Willment Daytona Coupe, SC2131. Waternecks can be ordered with right or left exit (left exit shown). Early-style clamps are included. Billet aluminum inline thermostat housing is supplied in natural aluminum, can be painted black, and accepts a GM thermostat. The one-piece, machine-crimped fuel harness with special brass fittings is just like the one supplied in the 60's before the advent of braided stainless hose and -AN fittings.

Cobra LinkageCenter Linkage

Linkage system on the original 289 Cobra roadsters operated off a center-shaft, and is faithfully reproduced. A 5/16" stainless steel shaft rotates in spherical rod ends screwed into in the intake. Note in photo at right that the activation point for this system is at the back, not via a side-mounted bellcrank. As with all systems built here, a return spring and an extra stop lever are also included on each assembly for safety. This is the only type of intake manifold linkage that will work on a 289 Cobra with factory-style interconnecting linkage as shown below.

Firewall Linkage

This throttle connecting linkage is reproduced from an original Weber-carbureted 289 Cobra, except the bell crank tower is now made from (thicker) 16-gauge stainless steel, and the linkage rods are also stainless. This 289 Cobra roadster throttle linkage kit will connect a 289 Cobra Weber unit to the mechanism at the foot box...if you have the accelerator assembly shown. Your car must have an original-style 289 Cobra foot box gas pedal assembly (note the gray housing at the lower right) mounted to the top of the foot box. A heavier-duty arm is also provided for the foot box, and is made in stainless as well. See the photos below, which show all the components in the kit.

Connecting linkage kit

Linkage Kit
The stainless bellcrank tower mounts to the back of the smallblock Ford cylinder head. Kit price is $325. Stainless hardware (not shown) is also included to mount the tower to the back of the cylinder head. The two linkage rods are also stainless. Tower will clear scattershields and has a strurdy brace on the back to avoid flexing.

Weber Linkage
This new 12-gauge stainless arm comes in the kit, and slips onto the 1/2-inch shaft on your accelerator pedal unit. It's much thicker than the original arm, to deal with the extra resistance of the 4 carburetors and the auxilliary return spring.

Firewall linkage kit

This is a linkage layout common to many other cars, especially the Superformance Cobras. Notice the transverse shaft that runs parallel to the firewall. If you have this layout, I can supply a longer 5/16" stainless shaft, clamp-on arms, and the connecting rod to the bellcrank to complete your installation as shown here. Just call with some simple dimensions and I will supply the linkage conversion parts to help you complete your conversion.

Shown is a standard inboard bellcrank layout, as supplied on all standard 351W Weber carburetion systems.

Fuel System Options: Competition and Street

The 289 Cobra FIA competition cars had a very unique waterneck that was hand-fabricated entirely from steel tubing with a fuel log mounted on top. This waterneck was exclusive to the competition cars, which all ran Weber carburetion. The fuel lines went to all 4 carburetors individually from the fuel log, rather than in a wrap-around harness, as seen on the street cars. This is sometimes referred to as the "octopus" fuel line setup. I now offer a 100% accurate reproduction of this unique waterneck, and the cost is $595. This is a 100-point, historically-correct item made from an original part (special thanks to Cobra Automotive, Wallingford, CT). Drawings for this piece are now stored in AutoCad to ensure a perfect reproduction each time. To the best of my knowledge, there is no other source on the planet for this part.

 Special banjo fittings are required on each carburetor for 3/8" I.D. hose (see photo below left). These fittings are not available anywhere, so I now have them fabricated and yellow cad plated; cost is $28 each. The parts for a real FIA fuel system are labor-intensive to make, and are a work of art. The FIA fuel line option isn't for everyone, but it's a must-have for anyone wanting a perfect FIA reproduction, and these parts are dead-on correct.

Fuel line details

Fuel Line Close Up
Here's a closer view of the special banjo fitting used on the FIA fuel systems. These are made by hand, and are the only fuel fittings for Weber carburetors that accept a 3/8" fuel line. A set of four of these fittings, plated in "yellow cad" are available for $112 ($28 each).

Fuel Line Close Up
Here's a close-up of what the fuel harnesses on the 289 Cobra street cars looked like during the 60's. I used to cut these off when doing restorations and replace them with this same setup. They were standard fare in those days, and today, I offer them again. You may choose between this style harness or the modern braided stainless harness with -AN fittings (although not period correct). The brass fittings are long-obsolete and I now have them custom made. There's no additional charge.
