1. 1967 Ferrari 330 P/4

2. 1966 Ford GT-40

The GT-40 will be mostly tuning, since the Slot.It car is pretty competitive right out of the box. The P/4 will need a lot more work; probably an HRS2 chassis underneath the body with the rockers / front end / back end migrated off the chassis and onto the body. Lay out...........well I'm thinking Scaleauto SC-0020 motors in SW configuration, 12:34 or taller gearing, might be good in both. Don't want to give one marque too much of a head start on the other...............
Let's see what you're thinking about.......
