The W Returns – Building a Chevy 409-CID “W” engine » MCP-0901-409-18

On the dyno the engine cranked out an amazing 497 HP and 525 lb.-ft. of torque after some significant timing adjustments.

The ignition system was installed using a Malloy coil and distributor as well as Taylor Cable wires and Denso plugs.
This engine is far superior to anything offered by GM in the heyday of the 409. Things like the Doug Thorley ceramic-coated Tri-Y headers are typical of the advancements made in generating excellent power and torque for this streetable engine.
