I was just speculating nobody knows for shure until GM releases full details. Ford on the other hand don't use high compression somewere in the 8.8:1 with FI motors and have a low 8psi-ish boost. GM on the otherhand might do what you have stated high compression and with 5psi boost. From some of the spy pictures it looks like it will have dry sump and with todays tech I think it will have E85. Looking at the pictures I think the L92 is Al.
