No that has no bearing on the situation (pun intended?).
First off the S62 block casting is different from the M62. It is stronger and also has larger bores (though these engines are likely bored and sleeved anway).
Secondly, these race engines are big bucks any way you slice it and the cost to source a block is absolutely minuscule in the grand scheme. They will use whatever works best and is legal.
