The rumored LS7 that that prototype crate engine is based on supposedly has a 4.11X" bore and a 4" stroke. That comes out to ~425ci.
The engine Jay Leno got might have had some custom parts inside to handle the boost but, the cubic inches will be the same for everyone if GM does actually put this engine out as a crate engine.
BTW, that is the next engine going in the '06 Z06.
