i have a 64 wagon factory 409 4 speed tachometer and dual exhaust how many of these were made?

Chubluv-- Over 13 million Chevrolet Impalas were sold from 1958 to 1966, more than any full sized car in automotive history. General Motors at the corporate level and Chevrolet at the division level, however, have no records which break those numbers as to specific options. Good luck from Bovan.

your 64 wagon is truely rare,less than 100,000 wagons were made. 7 engine and 14 different paint schemes were available. there were more red,blue and whites, than green, tan, or black. i myself own a triple black factory duel quad 409, for the last 40 years, this is an extremly rare number matching car, and its mint!! good luck jgbiker1@aol.com
