Edelbrock is excited to announce the release of its engine blocks for small- and big-block Chevrolet applications.

Edelbrock blocks are a great starting point for any high-performance build. A true American V8 engine deserves to be started with high quality iron cast in America! Edelbrock is now offering this option with new engine blocks that are cast and machined in the USA... and made to last! These are the same engine blocks used by Edelbrock for all of their small-block Chevy crate engines as well as their 540 RPM and 555 RPM big-block Chevy crate engines. The blocks are precision machined to Edelbrock's specifications, and they feature standard factory specifications for popular small-bock and big block applications. They also feature splayed main caps and priority oiling for improved performance and reliability.
