Has anybody done this before?

My Dart (shows below) is an original /6 car. I put those scoops on it, and I'm going to do a bumblebee stripe (I think) because I love the looks of it. It currently has a 318 in it, but who knows if one day I'll upgrade to a 360, or to a big block. Mind you I DID cut the holes in the hood to make them somewhat functional, but I took the 340 badges off the sides. But when people ask I tell them its a 318, and nowhere on my car does anything say 340.
