Q & A

What's in the Box

Said to be its most popular flathead intake, Offenhauser’s 2x2 Regular intake has closely spaced carbs that will clear the stock generator. The Offy regular dual intake accepts two 3-bolt carbs. Great addition to a street oriented engine. Has 4-3/4" carb centers.

Has room for generator in stock location, but generally requires an offset bracket. If using a GM alternator, use our chrome 916-67909 or plain 916-67910 bracket.

  • Carb Centers:  4-3/4"
  • For 1932-48 Ford Flatheads
  • Front drivers side accessory hole is for draft tube and measures 1.25"
  • Rear drivers side accessory hole is for oil fill tube and measures 1.375"

 

Notes

Specifically designed to fit 1932-48 models, which allowed Offy to move the carbs 1-inch further forward compared to the competitors intakes. This relocation was worth 2.8 more peak horsepower over the competitors but at the cost of 1.2 lb-ft less torque. Overall, the Offy had slightly better overall average power and torque numbers. This twin carb set up produces better numbers than Offy’s single four-barrel intakes.

Note: If used with our progressive linkage kit, the front carburetor will need to be set as the primary.

Just because you've got a vintage Flathead Ford V8 in your ride doesn't mean you're stuck with the antiquated charging system. Switching to a tried-and-true GM 1-wire alternator is a great upgrade for any Flathead-equipped vehicle with a 12-volt electrical system.

  • Bracket fits 1946-1953 V-8 engines
  • Heavy-duty steel construction w/ chrome plating
  • Designed to work with the two narrow-belt drive system typical of late '50-'53 Ford/Mercury passenger cars
  • Will not work with single wide belts unless the alternator is modified (see Notes)

9 Super 7® Primary Carbs -

Speedway Motors has incorporated many improvements in the 9Super7 Carb ® while maintaining the Stromberg 97 carburetor's original look. Features such as the choke assembly, accelerator pump, main jets and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result! Upgraded internal parts include; the float, needle, and seat. Jetting and power valve settings remain as they were for the original 97 carbs as well as the cfm and vacuum specs.

The 9 Super 7® makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required to do so with our kits is a Uni-Syn syncing tool and a little patience. Be sure to include the Secondary 9 Super 7 when installing 3-carb setups. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs.  See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7 in a 2x2 or 3x2 carb set-up.

On the primary 9 super 7 carb the throttle shaft extends from carb body .983" and has the hole on the end to pin the linkage. There is a brass sleeve that the throttle shaft rotates in that extends from the carb body .400 and this leaves the useable throttle shaft length of .583. There is sufficient room for progressive linkage and the manual throttle linkage that rotates over the sleeve. 

 

  • All-new tooling for crisp, flawless castings
  • New aluminum base assembly allows for cooler fuel temps and better fuel efficiency as compared to the original cast iron design
  • Stainless steel screws and hardware
  • Choke assembly, accelerator pump, and jets have all been faithfully retained and accept standard Stromberg parts
  • Features original Stromberg 0.97" venturi diameter
  • Modern Nitrophyl float and Neoprene gaskets
  • Original troublesome needle and seat replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improved high speed running 
  • Will not stick or dribble like the old Viton-tipped needle and seat setups
  • Grose-style jet valve won't corrode in modern fuel, something the original needle and seat units can do
  • Comes with a No. 65 power valve and 0.045" main jets, identical to the stock 97
  • Extended brass throttle shaft to simplify multi-carb linkage

Speedys 9 Super 7 Primary 3-Bolt 2 Barrel Carburetor, Plain Finish
                        

Speedway Motors now offers a reproduction version of one of the most popular carburetors ever used, the original Stromberg 97! Original equipment on '30s and '40s cars and trucks, the Stromberg 97 has long been favored by flathead hot rodders and racers who realized the performance qualities of this timeless fuel supplier.

There have been numerous attempts to reproduce this unit, with little success. "Speedy" Bill Smith of Speedway Motors in Lincoln, Nebraska, took on the challenge to make a great product even better. The 9 Super 7 ® Carb brings this reproduction of the original Stromberg 97 2 barrel carb into the 21st Century!

Speedway Motors has incorporated all of the improvements shown above while maintaining the carburetor's original look. Features such as the choke assembly, accelerator pump, main jets and cosmetics have all been faithfully retained. Additionally, each carburetor is individually flow tested and inspected for leaks. Perfection is the result! 

Aesthetically, the 9Super7 is nearly identical to the stock unit, minus the large 97 logo that appeared on the side and the patent numbers found on the float bowl area. Upgraded internal parts include; the float, needle, and seat. Jetting and power valve settings remain as they were for the original 97 carbs as well as the cfm and vacuum specs.

The other similarity that the 9 Super 7 shares with the original 97 is the setup and tuning necessary to yield a well-running machine. While perhaps not as simple as bolting on a single four-barrel, the 9 Super 7 makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required is an intake, a linkage system, a Uni-Syn syncing tool, and a little patience. Be sure to include the Secondary 9 Super 7 when installing multi-carb setups. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs.  See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7 in a 2x2 or 3x2 carb set-up.

Edelbrock 1103 38-48 Ford/Mercury Flathead Slingshot Manifold, 2 Carb
                        

Edelbrock has decided to re-release this legendary manifold; giving a new generation a chance to own this historic benchmark. Using a pair of two barrel carburetors mounted in a "Y" configuration, this manifold unlocked the potential of Ford's versatile flathead platform for thousands of enthusiasts across the country. The Slingshot manifold is designed for use with 1938-48 style Flatheads, some late model blocks can be modified to work with these heads. It works with standard three bolt Stromberg, Holley and Demon carburetors and allows for the use of a period correct generator mounted in the stock location. 7-3/4" tall. 

This is a reproduction of the original intake manifold designed by Vic Edelbrock Sr. in 1938. The Slingshot is a real show stopper and even includes stainless acorn nuts for mounting the two halves.  Among the first ever hot rod parts, the famous Edelbrock Slingshot still ranks among the best flathead intakes out there. The Slingshot produces more peak torque than the competitors two carb intakes, as well as more overall average power and torque. The ’38-vintage, two-piece Slingshot more than holds its own even today. If you want a high-rise, Edelbrock’s design is far superior. Includes assembly hardware and gasket #8700.  

  • For 1938-48 Ford/Mercury Flathead
  • Includes assembly hardware and gasket
  • 7-3/4" tall
  • Made in the USA
