New from Stromberg. Three cool stainless steel clips that solve so many hot rod linkage problems. There’s one for that pesky oversized Stromberg 97 choke ball so you can quickly convert it to cable operation. And two for the throttle linkage, to replace that spring-loaded old Ford piece that stretches open every time you accelerate!
Stromberg owner, Clive Prew, said “we’re all about about making Stromberg carburetors easier to use in more applications. And these smart new speed parts do that and more, in a cool traditional-looking way.”
First up, the new Stromberg Linkage Bomb (check the shape!), part 9164K-R and -L . They are sized to clip straight onto the bigger Stromberg throttle lever ball (most clips fit a 1/4in ball only). And they’re threaded 10-32 in left and right-hand versions for a 3/16in rod, with included lock nuts and small wrench flats for easy tightening.
Applications? Linkage Bombs are the perfect start for your hot rod pedal-to-carb linkage – use one right and one left and you can twist the rod to adjust the length. It’s also a straight swap onto that swaged end fitting on most hot rod throttle cable kits.
The Stromberg Rocket Clip (part 9166K) is a great new answer for that annoying Stromberg choke lever with its weird size ball! Just slide your choke cable or push/pull wire into the end. Fix it reliably with the the knurled set screw. And clamp the outer sleeve with a Stromberg 9552K-B choke bracket. If your hot rod throttle cable comes with a bare end, of course, the Rocket clip is the perfect answer.
New Stromberg Linkage Bombs and Rocket Clips are available from Stromberg dealers, worldwide. Prices are just US$15.99 and £8.29 plus tax where applicable. And you can click here to find out more at www.stromberg-97.com

We’ve worked hard this year on new solutions for Stromberg 6×2 set-ups, and here’s another smart idea that makes things even easier. Stay with us. It’s complicated!
Banjo fittings have always seemed a clean solution for 6×2 sets because you can run just two simple hose lines to the back of the engine and fit a fuel block on the firewall. Yet you never see it with progressive linkages. Why? Because progressive linkages with banjos also need banjo spacers to move the feel line away from the long center lever arm. But if you do that, you get into another issue, as the progressive linkage sliding rods on each bank must pull the front carbs open, because of clearance issues with the back-bar. And the sliding rod hits that banjo spacer.
Our new 9086K-C Banjo Spacer with Clearance solves that issue. Fit one to each center carb on your 6×2 and you will provide clearance for the forward-facing sliding rod. Job done! Of course, this also works for 3×2 linkages if you need to configure it in the same way. Check the new pieces out on our website and speak to your Genuine Stromberg dealer today!
We’ve been talking about our new BIG97 for far too long already. But now they’re available. Here’s the press release to start with. And we’ll be posting far more (i.e. everything we’ve got!) in the coming days and weeks. Please stay tuned!
May 2015. New BIG97 makes traditional carburetion available to a new performance audience.
Stromberg Carburetor is excited to announce the all-new BIG97 Tri-Power. On the outside, it’s all Genuine 97 – the original hot rod 3×2. But on the inside, an incredible 750cfm air flow makes traditional hot rod carburetion available to a whole new performance audience. Designed on the classic Primary/Secondary format with many new and exclusive features, the all-new BIG97 Tri-Power is the perfect bolt-on for your performance small block Chevy or Ford.
- BIG 750cfm airflow – 55% more air than regular 97s
- Signature 97 outside shape – No change!
- New power valve circuits improve fuel conditioning
- New ‘early plenum effect’ boosts top end power
- Ported distributor vacuum adds mid range torque
- Progressive linkages and classic 3-into-1 fuel line available
- Runs out of the box. Pre-jetted for typical SBC/SBF
Stromberg owner, Clive Prew said: “With 750cfm in a three-carb package on a progressive linkage, you can cruise economically on the single Primary, then punch in the Secondaries when you step on the gas. BIG97s reduce the level of vacuum the engine has to pull to get the air it needs, which promotes higher air/fuel density. They also reduce mixture velocity which allows that denser, fuel-heavy air an easier, less turbulent, turn into the inlet manifold. Coupled with improved fuel conditioning, it all adds up to more power for your rear wheels.”
From the outset, Stromberg’s aim was to re-engineer the 97 venturi and throttle body to maximize airflow without changing the signature outside shape. But achieving as much as 250cfm per carburetor – some 55% more than a regular new 97 (at 162cfm) is only part of the story.
The BIG97 Primary carburetor has a new power valve, located in the fuel bowl. Feeding top end enrichment directly into the emulsion tubes, it significantly improves fuel conditioning for more horsepower on less fuel. How? Because the more it emulsifies the fuel, especially at high rpm when manifold pressure is low, the easier it is to atomize, distribute and burn. At the same time, an oval cut-out, just under the throttle plates (Stromberg’s ‘early plenum effect’ ) coupled with our recommended intake manifold modifications, boosts top end power by slowing the mixture down and allowing any cylinder to draw from both barrels.
BIG97 Primaries also come with a swap-in fitting to provide ported vacuum for your aftermarket distributor, improving combustion efficiency in cruising mode for more torque and improvements in fuel mileage too.
Finally, everything that’s made the Genuine Stromberg 97 so popular over the past ten years is built into the all-new BIG97: An early style cast iron base for low heat transfer. A reinforced air horn casting to eliminate warping and leaks. High tech gaskets. Stainless steel levers, linkage and springs. Original-style riveted throttle and choke shafts. And more.
Stromberg BIG97 Primary and Secondary carburetors are available separately or as a ready-to-run Tri-Power (one Primary and two Secondaries), with extra savings available on packages with Stromberg’s exclusive Small Block Chevy linkage and fuel line.
