The new old cars got a lot of attention. Other appointments include the Autotrend EFI with a Holley HP ECU, an electronic ignition housed to look like a vintage magneto (possibly a Vertex), an MSD coil, cloth braided spark plug wires, while the juice is derived from the trunk-mounted Optima RedTop battery.
