OK...now that we have all of the "coke bottle" B body groups attention....Here is a question

As alot of you know...Mine is a Legit V code, with alot of documention and was wearing original paint when i bought it in 1979

The question is: What criteria determines the fender "engine call out" decal, Mine had the straight "440" on it and i`ve seen many original V code cars with the same, BUT...i`ve seen just as many with the 440+6.
I used the 440+6 simply because i like the look..and wasn`t as concerned at the time with absolute correctness.

I`ve done alot of research on 71`s but i`ve never been abale to get a straight answer to this.

Any thoughts

Rick
