EVOLUTION: A handful of Rolling Bones’ project cars tend to change over the years. Take William Medcalf’s ’30 Ford coupe, for example. In its previous incarnation, when owned by Tommy Ellis, it had a distinctive track nose. The roof makes the vehicle immediately recognizable, as it mixes pieces from a ’36 Ford, ’46 Ford, and ’48 Mercury. The ’57 Y-block Ford delivers about 400 horses.
