Crossover Headers 1-5/8- 1-3/4 Crate Motor

The Schoenfeld Crossover Headers 1-5/8" to 1-3/4" Crate Motor (model 135VHCM-3) is a specialized exhaust manifold system designed specifically for small block Chevy crate motor installations and high-performance engine swap applications. These headers are engineered to optimize exhaust gas flow, making them ideal for both naturally aspirated and forced-induction builds.

Featuring a conventional crossover design, these headers consolidate exhaust gas flow from both cylinder banks into a single collector, which enhances scavenging efficiency and reduces back pressure. Weighing 31.1 lbs, the headers are designed to fit into tight engine compartments without sacrificing tube diameter or collector design, ensuring optimal performance.

These crossover headers are particularly beneficial for builders looking to transition from factory small block manifolds to dedicated performance exhaust systems. They are suitable for various applications, including LS swaps into classic vehicles and both carbureted and fuel-injected crate motor builds, making them a versatile choice for automotive enthusiasts.
