Holley has announced the release of Tri-Power intake manifold and carburetor systems for small block Chevy engines. The Holley Tri-Power Carburetor System is well-known 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.
