MEET THE ENGINE BUILDER

Pat Musi’s reputation for winning began in ’71 on the streets of Queens, New York, at the wheel of a souped-up ’55 Chevy. He wisely transitioned from the streets to more legal forms of drag racing and following brief stints in the bracket and Modified ranks, Pat Musi rose to prominence as one of the fiercest competitors in Pro Stock and a true champion with 8 PDRA Pro Street World Championships.

Today, Pat brings that experience of driving a race car into the engine-building room at Pat Musi Racing Engines where many of the top Pro Mod racers go for their race-winning engines. As he has since 2004, Pat works exclusively with us to share his expertise in the Edelbrock-Musi Crate Engine Program that was created specifically for drag racers looking for big horsepower with unmatched durability.
