Copo Production & Survivors

[William]

The keeper of the info is Fran Preve, who works at the Tonawanda engine plant. They retained production records for many years. In an April 1987 issue of Muscle Car Review he stated that 822 "MN" and 193 "MO" code 427 engines had been shipped, 1015 total. As these codes are unique to Camaro, it is indicative of a production level near that number. He stated that historically, installation rates were 2%-5% less than engines produced.
