BMP 409 W Block

The wait is over. The first new 409 "W" Blocks since the sixties are in production, ready to blaze a new chapter in 409 history! This block represents BMP's biggest and most complicated R&D project to date. The 409 is an incredibly hard design to machine. We have done it in 357T6 Aluminum with Ductile Iron sleeves custom cut to shape and size.

For years 409 owners have had to depend on junkyard blocks to rebuild or replace tired 409s. The last 409s were cast iron version, made in 1966!

The 409 features an in block combustion chamber that requires 7 times the time to machine than a conventional Big Block Chevy Block. Designed in concert with Lamar Walden, the world's foremost expert on 409s, this ALL NEW W block uses mostly standard Chevy Big Block Components, making your build easier and more economical.
