At race day Porky finds himself up against famous stars such as Laurel and Hardy, and Charlie Chaplin. Porky also finds himself having to beat Black 13, driven by Borax Karoff, and hope to make it to the finish line.
When this cartoon aired on Nickelodeon, the scene at the beginning of the race where all the drivers speed off was cut to remove the part where a vehicle driven by Stepin Fetchit (a black character actor known for playing shiftless, lazy black men) trails behind them. Cartoon Network also edited this scene, but only in their computer-colorized version (which is also the version that airs on Boomerang). However, some airings of the computer-colorization were uncut. The black-and-white version they once showed on the installment series Late Night Black and White was uncut.
In the redrawn colorized version of this cartoon, the cartoon opens with the W7 logo with its 1967-1969 fanfare playing, and the W7 closing titles play the 1955-1964 Looney Tunes theme instead of the original ending theme to the cartoon.
