See i'm torn on the "correct liter badge" thing. On one hand, i still consider a 5.0 Mustang a 5.0 Mustang even if it's stroked...because to me the 5.0 part is more about the name of the car than the actual liter of the engine, but then at the same time it is a little misleading. I haven't put any on mine yet, i'm not sure if i want 5.0 or 5.7 badges.
I vote 5.7!
You know how you can get those badges that have "347" in big letters and "STROKER" in smaller letters at the bottom? I always thought it'd be funny to have a badge that had "5.0" just like the stock badge, but have "(based stroker)" in teeny tiny text underneath, haha.
