According to The Standard Catalog of American Motors 1902-1987, the AMC V8 was introduced on March 5 (1956) in a new model called the Hornet Special. It displaced 250 cu. in. The 2 V8 engines were sold side-by-side until October 25, when the 1957 models were introduced. The 1957 cars, all of which were called "Hornets", came _only_ with the 327 cu. in. AMC V8 (the Hudson and Nash 6 cylinder engines were no longer available).
