Check out our newest product! Part Number 9168K. Two threaded linkage ball studs with 7mm (0.275in) diameter balls – the same as Stromberg choke and throttle shaft connections. These handy new Stromberg linkage products feature half an inch of thread and nuts are included. Price is US$15.95 or £9.95 depending on where you live.
Use Linkage Ball for Cable Throttle
So where do you use them? For hot rod throttle cable connections! At 0.275in diameter, (others are only 0.25in) Stromberg linkage balls are designed to work perfectly with our 9164K Linkage Bombs and 9166K Rocket Clips. Check out these two applications below. Some aftermarket throttle cables come with a bare cable – use the 9166K Rocket Clip. Some come with a threaded connector swaged to the end of the cable – use a 9164K-R Linkage Bomb (with a right hand thread).
On both applications you simply insert the Linkage Ball in place of the small set screw in the end of the swivel on the lever you are pulling. It clamps the linkage rod perfectly – you can use the small hex on the ball to tighten it. Both use the same 10-32 thread. The lock-nut is supplied for other applications as required.
Here, they are pictured with Stromberg 9091K lever arms (as part of a TwoStep 2×2 direct linkage), and a 9136K Cable Throttle Mounting Bracket.
Norm Schenck at Competition Fuel Systems has been dyno testing Stromberg 97 and BIG97 carburetors for us for year. In fact he had a major hand in developing the BIG97 from scratch.
We set up a dedicated dyno motor at Norm’s facility in Vassar, Michigan and we’ve been watching intently as horsepower has grown with small tweaks to the carburetion and heads. This set up is with the cast iron vortec heads, that Norm ported himself. We have a set of AFR CNC ported heads waiting in the wings and they would probably make more power, but Norm suspects that the limitations of the Edelbrock tri-power intake would not have allowed for much more flow than was achieved with the vortec heads.
Want to know the numbers? This is a GM 330 horse crate motor and the best we got this time (by taking off the mufflers) was 404 ft-lbs of torque at 4300rpm and 386HP at 5400rpm. We still made over 400/380 with the mufflers on. This was on 89 octane gas with top end A/F ratios all in the 13s ! The dyno can now read separate A/F ratios per cylinder.
What this motor will do once someone (ie us) develops a new intake for the BIG97s is anyone’s guess. But it will be impressive, you can be sure of that…
These are pretty special. Based on Al Teague’s iconic Bonneville Roadster, artist Dan Wright has made just four of these beautiful pieces so far. They’re 18″ long, 8″ wide and lost wax cast in Stainless and Bronze. Besides being a piece of investment grade art, they are cast hollow to be usable as an urn with an o-ring sealed access panel in the underside. We may not be planning our departures quite yet, but we can’t think of many better places to while away our forever years.
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 (0.275in) 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, especially when used with our 9168K 0.275 inch diameter Linkage Ball.
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
