Info

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.

  • Converts 3 "small base" Rochester 2G/2GC main bodies into progressive Tri-Power
  • New base plates for secondary outboard carbs
  • Extended throttle shaft and butterfiles for primary center carb
  • Includes necessary plugs and hardware to recalibrate circuits
  • Includes adjustable mechanical progressive linkage
  • Linkage works with 3x2 intakes that have 5-1/2" carb centers
