The L92,LS3,and LS9 are all the same casting as of 2008. The L-92 has DOD, the LS9 has piston oil coolers ,deck plate honed and bigger dia. head bolts. The LS3 is just the updated casting of the old L-92. The L-99 has AFM (new term for the old DOD) and VVT. The bore on these are 4.065 with a 3.622 stroke.
