Description
If you’re running a dirt late model with a small block Chevy engine, header choice directly impacts exhaust scavenging and overall power delivery. The Beyea SBC Tri-Y DLM Spreadport is engineered specifically for this platform, optimizing primary and collector sizing to maximize flow without sacrificing mid-range torque—critical for dirt track performance where responsive power matters. This bolt-on kit eliminates guesswork and delivers measurable gains in both horsepower and throttle response.
