So after reading about the Solstice GXP, I got to considering potential for a dohc hybrid head. anybody know the specs (bore spacing, etc) of the ecotec? Even if possible, its a cinch I'd never be able to afford it. But, imagine the potential! direct injection.... turbo....

just an idea.

You might be better off going with a Vortech 4200 head, but the bore spacing is off (short) & they use a 3.66" bore.
