IIRC, that was a common exterior/interior color scheme for that Chevy and other brands through the years.
"She's real fine my 409...my four ohh nine..." There was a reason the Beach Boys made that motor famous - the first American muscle car that could beat a Jaguar E series at the time. "...my four speed, duel quad, posi traction 409...".
Ask a young man now what those terms mean. He'll look at you like you're from Mars. Hell, ask him what a generator regulator is, or a coil, or even a distributor cap.
Currently have a 1958 Chevy Impala 348 with tri-power. Amazed how much gas it sucks up, but thrilled to drive it down the road with the Ronettes blasting out the rolled down windows! Best design Chevy ever did. Got lot's of meets coming up. Hot August Nights! Screw politics for now. Haha.
A high school bud owned a ‘58 Chevy convert. It was a 348/4bbl/3 speed but would really scream.
LOL! My kid actually had me dissect all the terminology in 'Little Deuce Coupe' and 'Hot Rod Lincoln'...
Kids today like to brag it up... how much more power is coming off the factory line... They don't understand that back in the day, you could take a stock car and a few hundred bucks and make a fair ground-pounder (if you had the right connections and a couple duffers that had the knowledge).
Most every kid I knew back then had that ingenuity and drive. Nowadays they throw a chip in it, and everything else is about the sound system *shakes head*...
