L99 (4.3L)
The 4.3 L version of the LT1, designated the L99, was introduced in 1994 for the Chevrolet Caprice. It was externally identical to the LT1, but the bore was reduced to 3.736" and the stroke to 3.00" (similar to the late sixties Chevrolet 302 used in the first-generation Camaro Z28s). The pistons used in the L99 were the same as the ones used in the Vortec 5000 with the use of 5.94" connecting rods.
Like the LT1, it features sequential fuel injection, reverse cooling, and an optical crank position sensor. Output is 200 hp and 245 ft.lbf.
