Walker Cobra Series radiators boast a relatively thin, but efficient, high-flow copper core which is ideal for use with mild Small Block engines with stock or low compression ratios. Each radiator is built for a direct fit with heavy gauge steel side brackets and standard mounting holes pre-stamped. Plus, all radiators feature a built-in oil cooler for use with automatic transmissions. They work with original, reproduction, steel or fiberglass grille shells.
