SBC Header 602 Crate Howe 1-5/8in x 3in

The SCHOENFELD SBC Header 602 Crate Howe 1-5/8in x 3in (MPN 135HCM2) is a purpose-built header pair designed specifically for small block Chevy engine swaps and crate motor installations. These headers feature 1.625-inch primary tubes that transition into a 3-inch collector, engineered to optimize exhaust scavenging across a wide RPM range typical of street and bracket racing applications. Supplied with gaskets included and finished in durable black paint, this header set delivers the flow characteristics necessary for both bolt-in crate engine applications and custom engine bay conversions.

The 1-5/8-inch primary tube diameter balances low-end torque response with mid-range power delivery, a critical consideration when matching a crate motor to a vehicle's intended duty cycle. The 3-inch collector provides adequate runner length and cross-sectional area to prevent backpressure buildup while maintaining velocity through the transition to the exhaust system. Steel construction with black paint offers corrosion resistance suitable for both street-driven vehicles and track-prepared engines. At 30 pounds, these headers represent the structural durability expected of SCHOENFELD's header engineering, allowing for sustained high-RPM operation without warping or joint separation.

This header set is ideal for engine builders, hot rodders, and enthusiasts performing small block Chevy crate motor installations where OEM manifolds create packaging constraints or flow restrictions. The pair configuration serves vehicles requiring full dual exhaust routing, particularly in applications where header clearance or ground clearance demands the compact design geometry that quality aftermarket headers provide. Whether building a restomod, constructing a dedicated race engine, or upgrading a performance street engine, the SBC Header 602 Crate Howe delivers verified flow characteristics without requiring custom fabrication or modification to engine bay geometry.
