Hot rods first appeared in the late 1930s in southern California, where people raced modified cars on dry lake beds northeast of Los Angeles, under the rules of the Southern California Timing Association (SCTA), among other groups. This gained popularity after World War II, particularly in California, because many returning soldiers had received technical training. The first hot rods were old cars (most often Fords, typically 1910s-1920s Model Ts, 1928–31 Model As, or 1932-34 Model Bs), modified to reduce weight. Engine swaps often involved fitting the Ford flathead V8 engine (known as the “flatty”) into a different car, for example, the common practice in the 1940s of installing the “60 horse” version into a Jeep chassis.
Hot rod coloring sheets, If the coloring books of yesterday are fading away, coloring pages for kids on the internet have definitely taken their place.
