Line 5: =Generation III= The '''Generation III''' small-blocks replaced the LT family in 1998. These shared the same rough displacement and bore spacing (4.4 in) but ~~were~~much was changed. The bore was reduced to 3.9 in and the stroke longer at 3.62 in for greater torque. The block was cast from aluminum (for cars) instead of iron and had improved ignition and intake systems. The traditional five-bolt pentagonal cylinder head pattern was replaced with a square four-bolt design, and the pistons are flat instead of domed. ==LS1==
