There's nothing cooler than a TriPower on your small block Chevy, 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 3x2 kit also includes an adjustable progressive linkage kit for use on SBC intake manifolds with 5-1/2" carb center spacing.

- Includes necessary plugs and hardware to recalibrate circuits
- Includes adjustable mechanical progressive linkage
