General Motors V8 Generation II LT is a small block V8 engine. Making its debut in the 1992 Corvette - the new LT sought to draw upon the heritage of the 1970 Chevrolet LT-1.
A significant improvement over the original Generation 1 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.
Significant Problem: The early Optispark distributior.. which is located down the front of the dissy.. not up the back like traditional SBC V8's...the early 92-mid 94 LT-1's had durability problems and a revised version was introduced with vacuum vents to remove moisture on the 1994 B-Bodies and in 1995 on the Y and F-Bodies; the vacuum vents can be added onto earlier distributors
Some parts from the Generation II are interchangeable with the Generation I one-piece rear main seal engine. Their is various interchangeable parts.. including the rotating assembly (crank shaft, pistons, connecting rods, and flywheel/flexplate) and valvetrain assembly (not including timing set, which includes a gear to drive the water pump). The LT uses a new engine block, cylinder head, timing cover, water pump, intake manifold and accessory brackets. The harmonic dampener also does not interchange; it is a unique dampener/pulley assembly. Engine mounts and bell housing bolt pattern remain the same, permitting a newer engine to be readily swapped into an older vehicle.
