N2 - We combine the detailed Star Formation Histories of the Fornax and Sculptor dwarf Spheroidals with the mass assembly history of their dark matter halo progenitors to estimate if the energy deposited by Supernova type II (SNeII) is sufficient to create a substantial dark matter core. Assuming the efficiency of energy injection of the SNeII into dark matter particles is \epsilon=0.05, we find that a single early episode, z
