1969 Chevrolet Camaro COPO

1969 Chevrolet Camaro COPO 427/425 In the 1960s and 1970s, Chevrolet had specific rules for which engines could go in which cars. In 1969, when Chevrolet had a potent 427ci V8 on offer for the full size cars and Corvette, it was the rule that no engine larger than 400 ci could be fitted in a Camaro. But, some cunning Chevrolet dealers found a work around that became one of the most famous acronyms in automotive history. Instead of going through traditional channels to order new cars, for a few one offs, you could specify exactly what you wanted through a Central Office Purchase Order or as it became known - COPO. This process was more intended for fleet sales and speccing trucks to meet certain, edge case requirements, but ended up creating some of the all-time best factory produced hot rods.
