I bought four of these L92/LS3 crate engines, selling two of them. These are all-aluminum 6.2L engines, factory rated at 404 hp and 417 ft-lbs. They are complete intake to oil pan (for truck setup) and have exhaust manifolds, water pump, coil packs, fuel rails. No belt driven accessories, other than water pump.
These are the exact same shortblock and heads found on the LS3, you only need to swap the intake manifold and oil pan to the car types.
These are brand new
