Radiator Combo Unit GM A & G Body LS Swap

The Griffin Radiator Combo Unit for GM A & G Body LS Swap is a direct-fit cooling solution engineered for classic GM A-body and G-body vehicles (1963–1988) that have been retrofitted with modern LS engines. This aluminum radiator and fan assembly combines OEM-level fit with the thermal capacity required by high-output LS powerplants, eliminating the guesswork of custom radiator sourcing for engine swap applications.

The unit features a 33.25-inch width by 18.625-inch height core designed to fit within the original radiator mounting points of A and G-body chassis. Passenger-side inlet and outlet configuration ensures straightforward plumbing integration with LS swap harnesses and hoses. The aluminum construction provides excellent thermal conductivity while maintaining lightweight characteristics—critical for both cooling efficiency and vehicle dynamics. At 43.9 lbs, the complete assembly (radiator plus integral fan) keeps overall weight reasonable for vintage platforms where mass distribution affects handling and braking performance.

LS engine swaps into first-generation Camaros, Chevelles, Novas, Monzas, and similar platforms demand cooling systems that respect both the thermal output of the modern engine and the spatial constraints of original engine bays. The Griffin combo unit eliminates the time and expense of fabricating or hunting down used radiators, delivering a verified fit without custom modifications. This is the solution for builders and restorers who need dependable cooling without compromise.

The natural aluminum finish resists corrosion and suits both stock and detailed engine bay presentations. Whether building a weekend cruiser or a restomod with modern power, this combo unit provides the thermal management required to keep an LS engine running safely in a classic chassis year-round.
