Detailed fitment and design

Part number CCS-12 is a stock replacement camshaft developed for applications that call for original-style engine behavior rather than an aggressive performance profile. The camshaft specifications include 0.332 intake valve lift, 0.31 exhaust valve lift, 168 degrees intake duration at .050 inch lift, and 170 degrees exhaust duration at .050 inch lift. Valve lash is listed at 0.009 intake and 0.014 exhaust, with advertised duration of 288 degrees on both sides. This part cross-references Monroe Shocks & Struts (e.g., 3836490, 3836491) for the same application.

Compatible Chevrolet fitment includes 1950-1953 Bel Air, 1953 Corvette, 1953 One-Fifty Series, 1953 Two-Ten Series, 1946-1952 Fleetline, 1942 Fleetline, 1949-1952 Styleline Deluxe, 1949-1952 Styleline Special, 1946-1948 Fleetmaster, 1942 Fleetmaster, 1946-1948 Stylemaster Series, and 1942 Special Deluxe. CCS-12 is listed as an OE stock replacement grind, making it a direct match for stock-oriented rebuilds on Chevrolet engine platforms.

Common issues this camshaft addresses

• Worn cam lobes that reduce valve action and engine performance
• Loss of stock drivability after engine wear or teardown
• Need for an OE-style replacement during rebuild work
• Incorrect cam profile when restoring original engine behavior

Installation notes and quality

Install this camshaft during a complete engine service or rebuild, and verify lifter type, valve lash, and timing specifications before assembly. Because this is a solid flat tappet camshaft, proper break-in procedure and matched valvetrain components are important for correct operation. Melling develops, tests, and manufactures its stock replacement camshafts to OE replacement standards using quality materials.
