About Eight Stack

Looking for the ultimate induction system for your Ford Powered Cobra kit car, street rod or performance machine? What could possibly be more impressive than a quartet of 48mm downdraft carburetors perched on top of your small or big block Ford? If things like neck-snapping performance and supreme drive ability are also high on the list, the answer is easy: the new Eight Stack fuel injection combines all the visual impact of the original 48mm IDA carbs made famous by the Shelby Cobras with unmatched drive ability and performance. Unlike those cantankerous carbs, the new Eight Stack injection is designed to provide instant starting regardless of weather conditions, crisp throttle response and even impressive fuel mileage that comes with modern fuel injection systems.


The key to this impressive performance is the fact that the new Eight Stack combines nostalgic good looks with modern technology. Everyone knows that electronic fuel injection is superior to carburetion when it comes to catering to the fuel requirements of a performance motor. Thanks to todays sophisticated management systems Eight Stack fuel injection can be tuned to all but eliminate hard starting, plug fouling and the basically compromised air/fuel mixture associated with the original downdraft carburetors.


The ability to fine tune the air-fuel and timing curves is but one part of the performance equation, as the Eight Stack fuel injection also offers improved airflow compared to conventional downdraft carbs. With a combined airflow of over 2800 CFM, the new Eight Stack systems out-flowed its 48mm carbureted counterpart by an amazing 90 CFM per cylinder, for a total airflow improvement of just over 720 CFM! Imagine what your performance motor could do with and extra 720 CFM! Extensive dyno testing on Windsor and FE Ford applications have demonstrated that the new Eight Stack injection makes more power everywhere.

Bob's cobra features a 427 FE based 482 ci Stroker by Robert Pond Motorsports. Featuring 630 horsepower at the flywheel, Bob's Cobra packs some very deadly venom. Topped with the Eight Stack fuel injection system; the Cobra not only draws a crowd from the outside, but commands a strong presence with the hood up as well. Backing up the big FE mill is a 5 speed Tremec transmission allowing this Cobra to take to the highway with ease. The system is run off of a Precision Electronics Stage 3 ECU which handles the precise fuel delivery and timing. The car was wired and tuned by Tom Habryzk of Advanced Product Engineering in Camarillo, California and Robert Pond from Riverside, California. Fuel system was modified and the car was given the final touches by Tom Barnard of Speedway Classic Cars in Las Vegas, Nevada.
