Got a Chevy or a Ford with three 97s and an auto box? You need our new 9136K Cable Throttle Bracket plus our new Stromberg TwoStep progressive carburetor linkage with auto-trans kickdown capability.
What’s the secret? Our totally new center (primary) carburetor lever, which extends below the throttle shaft center line to pull the kickdown cable at a point set by the owner. The ‘kickdown’ end has a ¼”UNF thread, which accepts the special fixing common to most hot rod aftermarket auto-trans kickdown cable kits.
Linkages with the new kickdown capability simply add a KD suffix to the regular part number, so the 9246PRO 3×2 kit for small block Chevy intakes becomes 9246PRO-KD with kickdown. For small block Ford, choose 9253PRO-KD. Chrome versions are also available. All KD linkages come with two of our Snapback torsion-type throttle return springs, by the way. We have shown the traditional springs in our ‘assembly’ pictures to highlight a typical conversion from a Lokar-equipped 4-barrel carb to three 97s.
To be honest, kickdown is an issue we rarely encounter with flathead Ford applications, but with more hot rodders choosing a 97 tripower for their small block Chevy or Ford, our new ‘kick-down compatible’ progressive linkage, coupled with our new 9136K Cable Throttle Bracket, is a real problem solver. Just one note, if you have one of the more modern auto-transmissions like the 700R4, for example, please seek professional advice about the TV cable requirements. It’s not as simple as with an old-style Turbo 350, for example, as the rate of cable ‘pull’ is as important as the distance pulled. We are looking at special solutions, but they’re not ready right now.
Here’s the full KD range, available from stock. The new center carb lever (Part No: 9096K-KD) is also available separately, complete with swivel and clamping screw. If you need something else, please ask!
9246PRO-KD – 5-1/2″ carb centers – typical small block Chevy 3×2
9251PRO-KD – 4-7/8″ carb centers – Offy Y-block & Cad 3×2
9253PRO-KD – 4-3/4″ carb centers – Edelbrock small block Ford 3×2
