351c4v71 does stand for 351 cleveland 4 barrel 1971.
My first muscle car was a 71 Torino GT. Couldn't afford a 71 cuda.
But as soon as I could get my hands on a 71 barracuda, the Torino had to go.
I liked it though, laser stripes,color was similar to bahama yellow , louvers and hideaway headlights.
