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.

These Walker are direct replacement dimensions for the Ford Model T’s. The 820C4811 has the upper hose outlet centered and the lower outlet on the passenger side or Chevy configuration. The 820BC has upper in same location and lower on drivers side or Ford pattern. Both have the dummy neck on top to accept the standard T caps and decorative fixtures. They fill on a rear neck and both have the automatic transmission coolers. These Cobra radiators are for a basically stock small block motor. Big blocks or other than stock require the “Z” series radiators.
