"General Motors' Generation II LT is a small block V8 engine. Making its debut in the 1992 Chevrolet Corvette, the new LT sought to draw upon the heritage of the ultimate small-block, the 1970 Chevrolet LT-1.
A significant improvement over the original Generation I V8 is the Generation II LT's "reverse cooling" system, allowing coolant to start at the heads and flow down through the block. This keeps the heads cooler, affording greater power through a higher compression ratio and greater spark advance at the same time it maintains higher and more consistent cylinder temperatures.
Some parts from the Generation II are interchangeable with the old Generation I engine. The interchangeable parts include the rotating assembly (crank shaft, pistons, and connecting rods) of the Generation I small block with the one-piece rear main seal. The LT uses a new engine block, cylinder head, timing cover, water pump, intake manifold, accessory brackets, and front-mounted "Optispark" distributor. Engine mounts and bell housing bolt pattern remain the same, permitting a newer engine to be readily swapped into an older vehicle."

"In 1992, GM created a new-generation small-block engine called the LT1, similar to the high-output Generation I LT-1 of the 1970s. It displaced 5.7 L (350 cu in) and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower cylinder temperatures and allowing the engine to run at a higher compression than its immediate predecessors.
