There's nothing cooler than a TriPower on your small block, but man are the carbs expensive and hard to find!

With this kit you can use three junkyard 2G small base style Rochester carbs and put together a set-up for a fraction of the cost.  Includes two rebuilt bases for the secondary carbs, gaskets, jets, power valve and modified piston, idle tubes, plugs, hardware and new primary throttle shaft and butterflies. This kit includes an adjustable progressive linkage kit.

  • Bases are small pattern 1-7/16" throttle bores
  • Mount stud pattern is 1-7/8" x 3-1/4"

Makes it possible to convert old 2 bbls

By Puddle from Rapid City, SD on 4/9/2010
Pros:
Good Quality, Very cool
Cons:
Not complete for old carb, Return springs too strong
Best Uses:
Cool hot rods

I would only recommend this kit to a patient and knowledgable enthusiast or someone with a good bit of carburetor experience. I found it necessary to reset the butterflies in one of the baseplates. Throttle return springs are way overkill. When stepping on accelerator, feels like stepping on a rock. Full WOT is not always achieved as the linkage is deflected. Primary jets supplied were too big for my application. I started with 4 sizes smaller and may go a size or two smaller yet (mild 307 running at 3000 to 6000 feet asl). It would be nice to offer a kit that includes accelerator pumps and needle and seats for folks like me that started out with old 2 bbls that need rebuilding. But in the end, it made it possible to convert 3 old Rochesters for use as a tri-power system and performance, once I leaned out the center carb, is awesome! And boy does it look and sound cool!
