This large oval race set, released in 1978, is the Thundershift Roarin' Raceway. The set came with two cars. It usually came with the Hot Bird and the Race Bait 308 but can have random 1978 cars in the box. The track had two lanes with a lever for each lane that made roaring noises when pulled. A pulled lever flung the car around the track. When the car returned you had to pull the lever again to keep it going around the track.
