Dirt Late Model Headers Crate Motor 1-3/4 1-7/9

The Dirt Late Model Headers Crate Motor 1-3/4 1-7/9 by Schoenfeld delivers the exhaust scavenging efficiency that competitive dirt late model racers demand. Purpose-built for small block Chevy crate engines, these headers are engineered to maximize power extraction from entry-level racing platforms where every horsepower gain translates to lap times. Dirt late model racing relies on consistent, reliable exhaust flow to maintain combustion efficiency across the RPM range, and these headers address that requirement with precision-engineered primary tubing and collector geometry.

Constructed from steel with durable black paint finish, the Dirt Late Model Headers feature 1-3/4 inch primary tubes that transition into 1-7/8 inch secondaries before meeting at a 3-inch collector. This stepped primary design balances low-RPM scavenging with peak power delivery, preventing backpressure from stealing cylinder filling at high engine speeds. The collector diameter of 3 inches provides sufficient cross-sectional area to prevent exhaust gas velocity collapse while minimizing turbulence. Each pair ships complete with all gaskets and mounting hardware, eliminating guesswork during installation on your small block Chevy crate motor setup.

Racers running budget-conscious crate engine combinations benefit most from headers specifically tuned to that platform, and the Dirt Late Model Headers deliver proven performance gains without requiring custom fabrication or trial-and-error tuning. Installation fits standard small block Chevy engine bays found in dirt late model chassis, and the black powder coat withstands thermal cycling and track-day corrosion. Pair these with a properly-sized exhaust system and tuned intake manifold to unlock the full potential of your racing engine.
