Just cooked it up(i'm no artist),use proper Valiant style, switch 383 for 400. In the style of the rump stripe.
Sorry, my wife told me to "rotate", thought she was just ticked off.

pretty good but i think iam going to go with the strip and a valiant cut out, i change engines more than my underwear so i better just put valiant lol

is there anyone who knows how to make my picture have the stripe i want? photo chop or whatever it is you do thanks
