In racing, where every millisecond counts and horsepower rules, off-the-shelf engines only take you so far. Surprisingly, many modern race engines—even the massive 830ci Mountain Motor Pro Stock builds—still rely on designs from the 1960s.

At JHE, we asked a simple but bold question: What if we built something better—completely from scratch?

That mindset helped power Jason Scruggs to his 2015 PDRA Pro Extreme National Championship.

It began with refining a Brad Anderson engine—upgrading the camshaft and rocker systems for more output. Then we took things further, working with unfinished engine blocks to customize key components like cylinder and lifter bores, giving Scruggs a competitive edge.

But for Joe Hornick, that was just the beginning. To keep Scruggs ahead of the pack, JHE designed a fully custom race engine from the ground up. Every detail—from airflow to fuel delivery—was built with precision and purpose.

The result? A JHE-built power unit that carried Scruggs through a successful 2017 racing season.
