65 409 Impala on overhaulin'

[Verne_Frantz]

425hp for '63: there were 4,383 domestic and 11 export. For '64: there were 1,986 domestic and 11 export. Odd that the export numbers are the same for both years.
Unfortunately, Chevrolet did not collate option information by RPO# in '62, so there is no record of 380hp vs 409hp production that year. Only the total of 8,909 409s is known. There has been another '62 production number floating around in various publications of 15,019. That number is the total Tonawanda production for the year.
