670 CFM - Vacuum Secondaries - Shiny - Gasoline - Electric Choke

A smart match for small- to mid-displacement street builds, the 670 CFM Brawler Diecast uses lightweight aluminum castings to shed heat and weight while delivering modern fuel curve calibrations for today’s pump gas. Vacuum secondaries make transitions seamless and keep part-throttle cruising smooth, while the electric choke handles cold starts without fuss. You still get real tuning headroom—jets, bleeds, and mixture—so you can tailor response from idle through the mid-range, all in a reliably built, USA-assembled package.
