I am curious, my 67 6 cylinder has hood badging of "overhead cam 3.8 liter"
what makes this curious, is that all other birds are tagged with 326 or 400 - which of course is cubic inches.

Any idea why the 6 got metric 3.8 liter badges and not 230 cubic inches?

they were marketing the OHC as an alternative to a European sports sedan.

Thanks, that sounds like the sensible answer
