Radiator GM F-Body 70- 81 78-87 G-Body LS Swap

The Radiator GM F-Body 70-81 78-87 G-Body LS Swap by FLUIDYNE PERFORMANCE is designed for engine builders undertaking LS engine swaps into classic General Motors muscle cars and intermediates. This radiator is specifically engineered to meet the thermal demands of modern LS powerplants, which generate more heat than traditional small-block or big-block engines. It fits within the original mounting locations of second-generation F-Bodies (Camaro, Firebird) and A-Bodies (Chevelle, GTO, Cutlass).

Constructed from aluminum, this radiator features a high-efficiency multi-pass core design that maximizes heat rejection while maintaining a compact footprint. The aluminum core is resistant to corrosion and enhances thermal conductivity compared to copper-brass designs. The tank layout and inlet/outlet positioning are optimized for LS swap plumbing configurations, ensuring effective coolant flow.

This radiator is ideal for those converting 1970–1981 F-Bodies or 1978–1987 G-Bodies, where cooling system capacity and efficiency are critical for reliability and performance. By integrating seamlessly into vintage engine bays without requiring modifications to body panels or chassis components, it enhances the longevity and horsepower delivery of your LS platform. Whether you're running a naturally aspirated or forced-induction setup, this radiator is a vital component for your build.
