No, we haven't nailed it down yet. Here's the list of suggestions:

1. road runner be chased by wile e. coyote on an acme rocket
2. road runner with flames for a trail
3. a realistic "Roadrunner" logo painted towards the front of the lid. Then put another bigger Roadrunner on there with a giant claw grabbing at the logo...with flames getting heavier going back towards the back of the lid
4. Maybe have the coyote hiding behind an acme box pushing the plunger on a bomb and integrate the real fire into the explosion
5. Have a wild-eyed Wile E. hanging on to the front edge while being blown back over the front of the lid! You've already got the roadrunner on the valvecovers. (Tie design in with the valve covers)
6. Birds head (like '71 RR grille emblem), complete fire for fill in, with the outline and facial details in a lighter tone fire, so you have to look 3 times before you make out the full detail

Did you decide on a design for the air cleaner lid yet?

I'm really curious to see it espicially after seeing the cool work on the valve covers!
