1996 Caprice/Impala - Engines (L99)
4.3 Liter SFI V8 Engine (L99)
A 4.3 Liter small block V8 is the standard engine for the 1996 Chevrolet Caprice Classic Sedan. The L99 incorporates the Corvette LT1's advanced technology in a smaller 4.3 Liter displacement
engine. It produces 200 horsepower at 5000 rpm and 240 lb.-ft. torque at 2400 rpm. OBD II ( On-Board Diagnostics Second Generation) is standard.
- The 4.3L V8 features a cast-iron block, for durability and reliability
- The cast-iron cylinder heads were designed for a
Sequential Fuel Injection intake manifold and reverse flow cooling system, providing maximum power
without sacrificing efficiency
- An air cleaner silencing system and induction tuning provide extremely quiet operation
- A new electric air injection reactor (AIR) pump reduces hydrocarbon emissions on cold starts without
the parasitic power loss and noise associated with a mechanical air pump
- The L99 shares many technical features with the 5.7 Liter LT1 engine described below.
The L99 V8 improvements for 1996 include:
- Exhaust manifolds have tri-layered stainless-steel exhaust gaskets which improve durability and reduce
exhaust leaks
- Recyclable copper-lead cam bearings replace the cadmium lead bearings used previously
- Low-resistance ignition wires and platinum-tip spark plugs are designed to improve idle quality and cold-start performance.
