And yes you could get a V6 sport stripe on almost any engine combo. Only 340S /383S had the call Out in the stripe. Obviously 440 was only in Cuda’ only.
225 to 318 could be ordered V6 but solid stripe only.
Here are examples of a 340 Formula S with the Sport Stripe and a 440 ‘cuda. The Formula S is an original survivor and the 440 ‘cuda was an original paint car before I restored it over 25 years ago.
