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.

Features:

  • Available sizes from 570 to 770 CFM to meet your needs
  • Available in both vacuum and mechanical secondary versions
  • All models have dual inlet fuel bowls with sight glass windows for safe and easy float adjustments
  • All models come with an electric choke for easy starting in colder climates
