1977-1987 Chevy/GMC Truck 21 Inch LS Swap Aluminum Performance Radiator. This is the radiator that is 21 Inch high overall and has the steam port for an LS Swap. External trans cooler recommended.
These COLD-CASE radiators are Tig welded 100 percent aluminum and absolutely beautiful. Don't buy a 3 or 4 row aluminum radiator! It doesn't cool as good as these oversize 2 row models. These radiators are original appearing and have the correct stamping. Once painted, you'd be hard pressed to find a difference over an original versus a COLD-CASE.
