The W Returns – Building a Chevy 409-CID “W” engine » MCP-0901-409-9

Lamar Walden developed a special grind hydraulic roller camshaft for the 409 using COMP Cams tech engineers. End play is a problem with these blocks, which often have excessive play and wear down the cam gear quickly. The cam thrust button is pressed into the timing gear cover to set proper play and avoid this problem.
