JBA 65-86 GM Truck 265-400 Carbureted w/A.I.R. 1-5/8in Primary Ti Ctd Cat4Ward Header

Starting with 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle serious performance upgrades on your GM truck. They're designed to replace restrictive factory exhaust manifolds, which can significantly increase your engine's power and efficiency. This is a substantial upgrade for vehicles like the Chevrolet C10 Pickup, El Camino, or GMC C1500 Pickup, especially when you're looking to get more out of your 265-400 cubic inch carbureted engine.

The headers are constructed from durable stainless steel tubing, which resists corrosion and stands up to the demands of daily driving, towing, or even racing. JBA's proprietary Firecone collector design is a key feature, using race-proven technology to maximize power and torque gains in the RPM range where you'll be driving most. The tubing is mandrel-bent for smooth airflow, and the extra-thick collector domes add to the overall robustness of the system. Each set includes factory-style emission connections and high-quality hardware to ensure a professional, leak-free installation.

This header set is designed for a direct fit on a wide range of GM trucks and cars from the mid-60s through the mid-80s, including models like the Chevrolet Blazer, C10 Suburban, and GMC Sierra. It's a well-built component that offers a significant improvement over stock manifolds, helping your engine breathe easier and perform better.
