Linkage for OTB Sling Shot intake

How about this new Stromberg linkage for the OTB Sling Shot intake? Or any other crazy 2×2 side-by-side carburetor application come to that – like the Frenzel flathead supercharger. In fact we have supplied a couple of made-to-order kits for those. But this is an off-the-shelf kit that will accommodate spacing of up to 6-11/16in. Kit 9263-D.

These are the highlights.

  • Complete 2×2 non-progressive linkage for ‘side-by-side’ carburetor applications
  • Unique low-line stainless steel brackets support the Back-bar shaft at four points for zero flex and positive operation. Oilite self-lubricating bushes and two small washers to take up any height difference in the base castings.
  • Stainless steel Back-bar shaft with two end stops to prevent lateral movement.
  • Two stainless steel links from the Back-bar levers with Stromberg Linkage Bomb clips (9564K-R) for attachment to the carburetors.
  • One Stromberg 9096K long lever, which can be positioned anywhere along the Back-bar shaft to align with your throttle pedal ‘pull’ point. Complete with swivel and clamping screw.
  • Easy to fit. Supplied part-assembled, with instructions!

Want to see the linkage in action? This was an earlier model, but the principle is the same. Twin-plug flathead motor built by Austin Speed Shop and Keith Tardel for our buddy Doc from Louisiana.

New Stromberg Linkage Ball 9168K

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.

 

 

Stromberg BIG97 dyno thrash

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…

All-steel Bonneville A Roadster !

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.
