The first run chassises, chassii -- frames -- were aluminum, magnesium came later. The orginal design also used the frame tubes for oil piping up to the front cooler. JWA did away with that the 2nd year of the car, and individually plumbed the oil lines.

The 16 was unfeasible because of weight and size. The length of the motor would have really changed the turning moment of the car, already sketchy under Piech's no wing 'drag is bad' philosophy.

Also, the 917's life was coming to an end under FIM rules. CanAm required a much better hp/ton figure which was only gained with turbos.

As for the length of the crank on the 16, that shouldn't have been a problem. On the 12s, power was taken from the crank at the middle of the engine. Crankwise, it was like havint 2 flat sixes end to end. They probably carried over this element over to the 16 as well.
