Need more info but only have VIN

If it didnt say twister or 340 on the back near the stripe, it was likely a dealer installed stripe backing 72 to doll it up s bit to move the iron. This was pretty common as I have seen 318 and slant sux 69 barracudas with 340S style stripes with no engine call outs in the stripes. Likely to doll up the car to move it off the lot.
