    Not an LS series...but it is very similar if I am not mistaken.

    LY2

    The Vortec 4800 LY2 is a Generation IV small block V8 truck engine. Like its LR4 predecessor, it gets its displacement from a 96.01 mm bore and 83 mm stroke. The smallest member of the Generation IV Vortec engine family, it is unique in that it is the only member of that family that does not feature either variable valve timing or Active Fuel Management. It is rated at 295-302 hp (220-225 kW) and 305 ftlbf (414 Nm) of torque for all applications.

    All the V8s in the new body style Chevy trucks since 1999 are LS based except the Diesels and the big blocks.
