    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. Built for a direct fit with heavy gauge steel side brackets and mounting holes pre-stamped. 

    Made to fit 34 Master and early 35 Master (which looks like the 34). Will not fit late 35 Master which looks like the 36 model and features a 2-piece (split) windshield, suicide doors, and a 113" wheelbase. Late 35 Masters should use the 36 radiator.

    • Copper core w/ 1-piece brass tanks
    • Vertical tubes every 1/4" and 17 fins per inch of height
    • Heavy duty 12 Ga. steel side brackets w/ pre-drilled holes
    • Use a 15-18 lb. radiator cap
    • Brass drain cock
    • Simple bolt-in install w/ no modifications to grille or grille shell
    • Built-in oil cooler for use with automatic transmissions
