The Holley LS Fest is a celebration of everything and anything powered by the incredible GM LS engine! If an LS based 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 - you name it, if it is being powered by an LS there will be something here for you! Take part in our drag race, autocross, 3S challenge, show-n-shine and more.
