Radiator Combo Unit GM A & G Body LS

The Griffin Radiator Combo Unit for GM A & G Body LS engines is a direct-fit cooling solution engineered for classic Chevrolet muscle cars and street machines equipped with modern LS-series powerplants. This all-in-one radiator and fan assembly delivers efficient heat rejection in a compact footprint, eliminating the need to source separate components and ensuring proper fitment in tight engine bays typical of 1968–1989 A-body and G-body platforms.

Constructed from aluminum for superior thermal conductivity and corrosion resistance, this unit measures 33.25 inches wide by 18.688 inches high by 6.438 inches deep. The passenger-side inlet and outlet configuration integrates seamlessly with LS-swap cooling systems, eliminating guesswork during installation. The integrated fan assembly provides reliable airflow across the core at idle and under load, a critical factor for vehicles driven in stop-and-go traffic or at cruise speeds where thermostatic control matters. The natural aluminum finish resists oxidation and complements period-correct engine bay aesthetics.

This combo unit is purpose-built for LS-engine swaps into classic Chevrolets—owners of Camaros, Novas, Chevelles, and Monte Carlos from the muscle car era who have upgraded to modern powerplants and need cooling solutions designed around tight original engine bay dimensions. Whether building a street rod, resto-mod, or weekend cruiser, the direct-fit design reduces fabrication time and cooling-system complexity while maintaining the visual authenticity of the original installation.
