I was talking about 1971 Hemicudas, and F8 was not available in 1971.
However, in 1970, F8 was not the most popular color for the Charger R/T. Check out
http://host219.ipowerweb.com/~1970ch.../RT_Codes.html and you'll see there are at least two other colors that were built in greater numbers.
Also, you'll see from that site that approximately 1452 Charger R/T SEs were built. If you apply (statistically incorrectly, might I add) the 1.2% of Hemi production to that, it comes to 17 or so, so I guess we know the number "14" doesn't come from that incorrect math.
