Holley LS Fest has become the go-to event for fans of GM’s high performance do-it-all LS engine platform. Holley returns to Las Vegas for the second year of LS Fest West, once again taking place at Las Vegas Motor Speedway. If an LS based (or current generation LT) engine is powering your ride or if you are considering a swap to LS power, this is your event! Race cars, street rods, muscle cars, trucks, late models, drift cars – you name it, if it is being powered by an LS there will be something here for you! Take part in our drag racing classes, autocross, 3S Challenge, Show-N-Shine, Dyno Challenge, Off Road Challenge and more! Event/class champions will be crowned as well as an overall event champion for those that want to compete in multiple events. Check out the rest of the site and make plans to join us!
