Dirt Late Model Headers 604 Crate 3 Step

The Dirt Late Model Headers 604 Crate 3 Step by SCHOENFELD are specifically designed for dirt track competitors utilizing GM 604 crate engines. These headers are engineered to maximize horsepower and torque by optimizing exhaust gas flow and reducing backpressure in high-RPM racing scenarios. Ideal for both new builds and upgrades, they cater to the needs of serious racers.

Featuring a three-step collector design, these headers utilize progressively sized primaries that align with the exhaust pulses of each cylinder group. This design minimizes reversion and enhances scavenging efficiency across the entire RPM range. SCHOENFELD employs precision mandrel bending and tube sizing to ensure consistent wall thickness and optimal flow characteristics, essential for reliable performance under high-heat conditions.

These headers are perfect for dirt late model racers and engine builders looking to enhance the performance of their 604 crate engines. The stepped collector configuration offers superior merge characteristics compared to traditional designs, leading to significant gains in peak horsepower and mid-range torque. This performance advantage is crucial for achieving faster acceleration off corners, which is vital in competitive dirt late model racing.
