Mooresville, North Carolina-based Pat Musi Racing Engines and Olive Branch, Mississippi-based Edelbrock Group has extended its longtime partnership through 2023.

The Edelbrock/Musi Signature product line, including the popular Edelbrock/Musi 555 crate engine and race-ready cylinder heads and manifolds, will continue to be developed and offered as part of the collaboration. 

“It means a lot to me to continue our partnership with Edelbrock,” Pat Musi said. “Vic Edelbrock taught me a lot about business and we had a great relationship, and to see it continue with their team for more than 20 years is a great thing.”

Product development will continue to be a key part of the relationship, the company stated. Operations are based out of the Edelbrock Race Center housed within the Pat Musi Racing Engines facility. All Edelbrock racing cylinder heads are machined using a Centroid 5-axis CNC.

“We’re going to really put our heads down and continue to concentrate on the race center,” Musi said. “There’s a lot going on and we’re always working on developing new things, so we couldn’t be more excited.”
