Finishing the prototype engine is a new serpentine belt-drive system. Unlike other systems on the market, this can be tailored to mount any combination of power steering, A/C, or dual alternators, without a bunch of additional "dummy" idlers. Lamar reversed the water pump to work with these. Note the humped spokes in the pulleys, inspired by the valve cover's shape. This set-up was hours old when we shot it, and wasn't completely finished.
