Holley Announces Tri-Power Systems for Small Block Chevy


Musclecars with multiple carburetors are a match made in heaven; whether you’re referring to an early Pontiac GTO, Hemi-powered Mopar or an L-89 BBC Corvette, seeing two or more carbs sitting on top of an aluminum intake can make any gearhead smile.

So when our friends at Holley Performance tipped us off on their newly-released Tri-Power carburetor system for small-block Chevys, we had to let our readers know all about it. You can get all of the specifications from the official release from Holley below.

Official Release:

Holley is proud to announce the release of Tri-Power intake manifold and carburetor systems for small-block Chevy engines.

The world-famous Holley Tri-Power Carburetor System is legendary in Chevrolet circles. It was factory equipment under the hood of the legendary big block L71 and L89 Corvettes.​ Holley has brought that look and performance to your small block Chevy. With the Tri-Power system, you can cruise around economically on the 350 CFM center carb or unleash all 1000 CFM at wide open throttle to truly have the best of both worlds.

Systems include a dual-plane, medium-rise 3×2 Weiand intake manifold, three Holley 2bbl carburetors (one 350 CFM center carb with electric choke and two 325 CFM outboard carbs) in either a dichromate or shiny finish, high quality steel fuel lines, progressive throttle linkage, and reusable air filters with chrome housings.

  • Includes dual-plane Weiand aluminum intake manifold
  • Carburetors available in either a dichromate or shiny finish
