LS and LT Radiator for 1964-1967 Chevy Chevelle/El Camino A-Body
Taming the extra heat of an LS or LT swap in a classic Chevelle or El Camino with a manual gearbox starts with proper cooling and the 1964-1967 Chevelle Radiator (Manual Trans) delivers. Its alignment with factory frame rails and use of manual transmission seal off plates ensures a clean firewall area without any custom brackets. The pure aluminum core features precision TIG welding for corrosion resistance and rapid heat rejection under heavy load. Designed for the A Body chassis, it maintains stable coolant temperatures during spirited drives or while towing.
Precision TIG Welded Aluminum Core for Enduring Strength
Each joint in this radiator is formed by TIG welding, a process that delivers uniform full penetration seams resistant to cracking under constant vibration. The choice of high quality aluminum provides impressive rigidity while preserving a light weight profile, so the assembly remains stable through repeated thermal cycles. Skilled welders in the USA complete each seam to exacting standards, eliminating common leak paths found in lesser units. This level of craftsmanship ensures the core maintains a perfect seal even under heavy towing loads or spirited acceleration. As a result, coolant stays contained and engine temperature remains consistent from start to finish.
Dense Parallel Flow Core Enhancing Heat Rejection
The core employs a parallel flow architecture that splits coolant evenly among multiple side by side channels, dramatically increasing the surface area exposed to oncoming air. Aluminum's excellent thermal conductivity draws heat away from the engine block at a rapid rate, keeping coolant temperatures stable during extended periods of high output. In practice, this design minimizes hot spots and reduces the risk of boil over when hauling a trailer or powering up steep grades. The enhanced heat rejection capacity is especially critical for modern LS and LT engines, which generate significantly more thermal energy than stock six or small block V8 powerplants. By maximizing airflow contact, the parallel flow core upholds reliable cooling under the most demanding conditions.
Engineered Fit for A Body Frame Rails and Transmission Seal Plates
Designed specifically for 1964 through 1967 Chevy Chevelle and El Camino A Body chassis, this radiator aligns precisely with factory frame rails and mounting points. It accommodates manual transmission seal off plates directly, avoiding any need for custom brackets or cutting to the firewall. That means installers can maintain a clean underhood appearance and focus on final adjustments rather than fabrication. The precise fitment preserves the vehicle's original firewall contours and bracket locations, ensuring a professional installation every time. With this direct integration, cooling performance is optimized from day one and factory style remains intact.
Dual Finish Options for Protection and Period Correct Style
Installers can choose a polished bare aluminum finish to emphasize the core's natural sheen and exploit aluminum's innate resistance to oxidation in dry climates. For vehicles exposed to moisture, road salt or coastal air, the black epoxy finish applies a durable barrier against corrosion without impeding heat transfer. Both finishes adhere tightly to the surface and withstand stone chips, UV exposure, and repeated temperature swings. This flexibility allows builders to match the aesthetic of a restored engine bay while delivering lasting performance. Whether preserving a showroom restoration or building a driver quality cruiser, the available finishes ensure the cooling system remains both functional and visually appealing.
