HISTORY: 262 / 4.3

[] 262 / 4.3L

3.736 in Bore

3.00 in Stroke

262 CID 1994-1996

  The L99 4.3 L (262 CID) V8 shared a 3.736 inches cylinder bore with the 305 CID but had a 3 inches stroke compared to the 3.48 inches stroke of the 305 CID. The pistons used in the 4.3 L V8 were the same as the ones used in the Vortec 5000, but 5.94 inches connecting rods were used to compensate for the shorter stroke. It was designated by the RPO code L99, and was introduced in the 1994 model year. This was the base engine used in 1994-1996 Chevrolet Caprice Sedans, the 9C1 police package sedans and the 1A2 special service station wagons. The L99 was not available in other vehicles.

  The L99 featured updated Generation II block architecture and is visually identical to the larger 5.7 L LT1 Generation II V8. Like the LT1, it features sequential fuel injection, reverse-flow cooling, and an optical ignition pickup. Output is 200 hp and 245 lb·ft . Due to its smaller displacement, the L99 provided higher EPA fuel economy ratings than the 5.7 L LT1. The L99 was produced for the 1994-1996 model years.
