I'm open to the spec, in the same way that the body has to be within the set volume.
But disagree that it has to go through group A first, 2,500 examples etc, when it's only the block being used - just a lump of metal - and road designed displacement is often ignored anyway as everything that bolts to it is made for purpose as it all transforms into a racing engine! With 10% by 2035 and manufs divesting their engine building because they don't want to be associated with them, the pool of potential suppliers is too small and the wrong crowd. And if a Horse can supply an engine (like it is supplying that Chevrolet a few pages back), why can't a pony provide engines that are built for purpose? That's the philosophy of all this.
It doesn't make sense. And market forces work so much better than cost caps on a very small group of disinterested suppliers.
