Seems to me that the motor challenges are about the builders and not about the engines. Since probably 97% of the readers could car less about how much power can be wrung out of a /6, I see why the magazines aren't trampling over themselves to devote the resources to it.
IMHO, any competition that does not include a comparative index of fuel consumption and durability doesn't do justice to the things that make the /6 a great engine. The engine got it's deserved reputation by being reliable and economical to operate. Besides, if the /6 were to become mainstream, look for supplies of parts to go the way of the E-body and shoot into the stratosphere.
