Headers for LS In 73-77 A-Body 1.875in Uncoated

The Headers for LS In 73-77 A-Body 1.875in Uncoated are designed for high-performance LS engine swaps into the 1973 to 1977 GM A-Body chassis. These long tube headers are essential for enhancing exhaust flow and providing the necessary clearance for modern small-block Chevy powerplants in classic mid-sized frames.

Featuring a 1.875-inch primary tube diameter, these headers are optimized for volumetric efficiency, making them suitable for high-displacement LS engines or those with performance camshafts. The 3-inch collectors are designed to improve exhaust scavenging, which can enhance overall engine performance compared to factory manifolds or shorty headers.

These headers are a fundamental upgrade for any LS-swap project, particularly for enthusiasts looking to maximize the performance of their 1973-1977 Chevelle, Monte Carlo, or Regal. Builders can trust the vehicle-specific design to ensure proper fitment and performance in their classic vehicles.
