I released Threefortysixbarrel on May 28, 2004, when I was exploring muscle car aesthetics. I had just begun working full-time as a type designer and wanted to capture the look of 1970s Plymouth Barracuda nameplates. The design was display-only, intended to echo the bold industrial lettering associated with cars built for speed.

I created three styles: a clean version, an “Intake” version with a corroded texture, and an “Exhaust” version with heavier wear. These were conceived as stylistic variants rather than direct reproductions of physical damage. The name came from the “340 six-barrel” Plymouth engine option, which seemed appropriate for a font tied to that era and culture.

From the beginning, the family was sold commercially and was never offered for free. On June 18, 2021, I updated it by removing deprecated characters, fixing space-width inconsistencies, narrowing the ellipsis, and smoothing some curves. Later that year, on November 18, 2021, I shortened the menu name from Threefortysixbarrel to 340sixbarrel to accommodate MyFonts’ system requirements. The typeface has not seen notable use, but it remains part of my catalog as a tribute to muscle car design language.
