Update if anyone is keen,
Yes the crank was fouled against the oil pump it also fouled against the block and girdle, so block and girdle are stuffed, also all bearings, mains and rods are scored and not useable the rods are not useable, oil pump hasn't gave way!!
What I can gather is, n1 oil pump as higher flow then stock and with no oil restrictors, larger sump or head drain while sitting on the limiter has left the bottom end empty and has caused all this damage,
As for the oil jets, there is no marks on the under skirts of the pistons to say the pistons hit it
