Since we are sharing opinions....

A nice looking single color Max Wedge style vibe is timeless and always looks good. Race car schemes on early B's rarely look good IMHO.

No matter what era of race car scheme you choose it will likely look dated, and/or it will look like you are copying someone else's paint scheme, ie Ramchargers, or Sox, Melrose Missle, ect.

Though it may seem unimaginative, choose one of the stock colors available in 1963.
- Paint the car 1 stock 63 color,
- Keep the chrome bumpers,
- Install a proper 63 style MaxWedge scoop,
- Use color keyed steel wheels, or a Torque thrust type front, steel rear combo.
- The slotted mags on there currently give a cool vintage vibe.

Think ahead several years...yes, it is unpleasant to think about selling, but unpleasant unforseen stuff happens. The future buyer will likely not share your vision of a "cool race car paint scheme."

Keep it simple.
