After reading the first link something just looks fishy to me. First the MMC (banned in F1) rod picture he posted is quite obviously not made for automotive crankshafts. That one would require a built up crankshaft because the rod end isn't separateable.

Also they watermaked that picture even though it's easy enough to find the original?

The billet block is straight off billet cylinder heads site also, they even photo-shopped off their logo:
