We love seeing our roller rockers hard at work in real-world builds like this stunning 429 long block fClinton Performance Machine!

This mild build for a mid-70s F250 features our precision-engineered roller rockers working alongside top-tier components from Howards Cams, ARP, and Edelbrock Performance. When you're building a classic truck engine that needs to deliver reliable torque and performance for years to come, every component in your valvetrain matters.

Our roller rockers are designed to handle the demands of both street performance and daily driving while maintaining the durability these legendary Ford big blocks are known for. Whether you're building a weekend cruiser or a work truck that needs to perform, we've got the valvetrain components to get the job done right.
Excellent work, Clinton Performance Machine – this build looks fantastic! 💪

Finished. Matched. Ready.

Every rocker is precision-finished and matched before it ever reaches your valvetrain.

Consistency under load starts here.

Tolerance isn’t visual.
It’s measured in thousandths.

Controlled geometry. Verified repeatability.
That’s the difference between assembled and engineered.
