Im not an expert but......

my car is constantly called a Chevelle, or ill be asked if it has a 440 Hemi in it. My boss insists that the Ebody Barracudas and Dusters are hard to tell apart. My friends Duster is always called a Nova. Once a guy told me he had an olds with "that big 442 in it" and i told him that they didnt have 442 engines and he said "yah they did" , ive just decided to agree with all these "car buffs" instead of trying to enlighten them
