What is the firing order for 1994 Chevy Caprice?

Answer 1

typically the firing order for a small block Chevrolet:
Clockwise 1-8-4-3-6-5-7-2


In 1992, GM created a new-generation small-block engine called the LT1, recalling the 1970 LT-1 moniker. It displaced 5.7 liters and was a 2-valve pushrod design. The LT1 used a reverse-flow cooling system which cooled the cylinder heads first, maintaining lower cylinder temperatures and allowing the engine to run at a higher compression than its immediate predecessors. This engine was used in:

• • 1992-1996 Chevrolet Corvette C4
  • 1993-1997 Chevrolet Camaro Z28
  • 1993-1997 Pontiac Firebird Formula and Trans Am
  • 1994-1996 Buick Roadmaster
  • 1994-1996 Cadillac Fleetwood
  • 1994-1996 Chevrolet Caprice
  • 1994-1996 Chevrolet Caprice Police Package
  • 1994-1996 Chevrolet Impala SS
  • 1994-1996 Chevrolet Caprice Wagon
  • 1994-1996 Buick Roadmaster Wagon

There were a few different versions of the LT1. All feature a cast iron block, with aluminum heads in the Y and F bodies, and cast iron heads in the B and D bodies. Corvette blocks had four-bolt mains, while most other blocks were two-bolt mains. The 92-93 LT1s used speed density fuel management, batch-fire fuel injection and a dedicated engine control module (ECM). In 94 the LT1 switched to a mass airflow sensor and sequential port injection. A new, more capable computer controlled the transmission as well as the engine and got a new name: powertrain control module (PCM). Where the ECM held its calibration information in a replaceable "chip", the PCM was reprogrammable through the diagnostic port. The early Opti-spark distributor had durability problems and a revised version was introduced on the 1994 B-Bodies and in 1995 on the Y and F-Bodies. 1996 saw major revisions for OBD-II - a second catalytic converter on the F-body cars (which was standard since 1995 in California), rear oxygen sensors to monitor catalyst efficiency and a crank position sensor for misfire detection. Some OBD-II features had been added to the Corvette starting in 1994 for testing purposes. The 1997 model year Camaro and Firebird were the last year for this engine in a GM production car. The 1992 LT1 in the Y-body was factory rated at 300 hp and 330 ft-lb. 96 LT1 Y-bodies were rated at 300hp and 340 ft-lb. The 93-95 F-bodies were rated at 275 hp (202 kW) and 325 ft·lbf (439 Nm), while the 96-97 cars were rated at 285 hp (210 kW) and 335 ft·lbf (452 Nm). The 96-97 SS/WS6 F-bodies were rated at 305 hp. The 94-96 B and D-body version was rated at 260 hp (191 kW) and 330 ft·lbf (446Nm).
