There's nothing cooler than a 3x2 intake on a vintage Chevy/Pontiac/Oldsmobile/Cadillac/Buick V8 engine, but good carburetor cores are getting expensive and hard to find! With this kit you can use three junkyard 2G small base style Rochester carbs and put together a three deuce set-up for a fraction of the cost.
Kit includes two brand new throttle body base plates for the secondary carbs, gaskets, jets, power valve, modified piston, idle tubes, plugs, hardware, and new throttle shaft and butterflies for the primary carb. This kit does not include throttle linkage, allowing you to customize the application to your specific needs.

Customers value the product for its quality and practicality in setting up Tri Power carbs on different Chevy models. Notably, the kit is appreciated for assisting in transforming manifold and carbs into a Three Deuce setup. Some consider it a time-saving solution for their projects. However, the product's usability may require prior tripower experience due to challenges with sealing the end base plate butterflies completely. The linkage is stated to be difficult to set up correctly especially with an electric choke on the primary carb. Adding the linkage was recommended as otherwise, the setup may not function correctly. Despite some functional challenges, the product is considered a complete kit with all necessary components. It also acts as a tasteful addition to the vehicles, contributing to their aesthetic appeal.

Very satisfied with the Rochester carburator bases that I purchased from Speedway. My 34 Ford Street Rod with tripower has never run as good as it does now!
