LT5 Series architecture, and utilize such modern technologies as individual ignition coil per cylinder and direct fuel injection.
Due to the wide range of small block applications, if you are retrofitting a previous small block application, you may encounter
installation differences between your crate engine assembly and the previous version. These differences may require modifications
or additional components not included with the engine, including cooling, fuel, electrical, and exhaust systems.
Some fabrication work may be required.
The LT5 crate engine require an engine control system which is available from your Chevrolet Performance Parts dealer. Check
with your dealer or on

protection and appropriate protective clothing. When working under or around the vehicle, support it securely with jack stands.
Use only the proper tools. Exercise extreme caution when working with flammable, corrosive, and hazardous liquids and materials.
Some procedures require special equipment and skills. If you do not have the appropriate training, expertise, and tools to perform
any part of this conversion safely, this work should be done by a professional.
This publication is intended to provide information about this crate engine and related components. This manual also describes
procedures and modifications that may be useful during the installation of an LT5 crate engine. It is not intended to replace the
comprehensive service manuals and parts catalogs which cover Chevrolet Performance engines and components. Rather, it is
designed to provide supplemental information in areas of interest to "do-it-yourself" enthusiasts and mechanics. This publication
pertains to engines and vehicles which are used off the public highways except where specifically noted otherwise.
Legal and Emissions Information
Federal law restricts the removal of any part of a federally required emission control system on motor vehicles. Further,
many states have enacted laws which prohibit tampering with or modifying any required emission or noise control system.
Vehicles which are not operated on public highways are generally exempt from most regulations, as are some special
interest and pre-emission vehicles. The reader is strongly urged to check all applicable local and state laws. Many of
the parts described or listed in this manual are merchandised for off-highway application only, and are tagged with the
"Special Parts Notice" reproduced here:
Special Parts Notice
This part has been specifically designed for Off-Highway application only. Since the installation of this part may either
impair your vehicle's emission control performance or be uncertified under current Motor Vehicle Safety Standards, it
should not be installed in a vehicle used on any street or highway. Additionally, any such application could adversely affect
the warranty coverage of such an on-street or highway vehicle.

  • Page 1 This publication is intended to provide information about this crate engine and related components. This manual also describes procedures and modifications that may be useful during the installation of an LT5 crate engine. It is not intended to replace the comprehensive service manuals and parts catalogs which cover Chevrolet Performance engines and components.
  • Page 2 Intercooler coolant pump The LT5 kit is supplied with a supercharger intercooler pump. A custom liquid to air intercooler must be incorporated within the vehicle to reduce the charge air temperature. If purchasing the Chevrolet Performance Parts (CPP) engine controller, it will have an electrical connector designed to fit the supplied pump.
  • Page 3 Iridium-Tip Spark Plugs: The spark plugs have an iridium electrode tip and an iridium core in the conductor, offering higher internal resistance while maintaining optimal spark density over its useful life. The electrode design improves combustion efficiency. 19417106 LT5 Dry Sump Engine Installation IR 03OC18 TITLE PART NO.
  • Page 4 A returnless fuel system reduces the internal temperature of the fuel tank by controlling the speed of the fuel pump and not returning hot fuel from the engine to the fuel tank. If using the Chevrolet Performance engine control kit, a pulse width modulation capable fuel pump that delivers 500 kPa (72psi) at 45 gallons per hour is required.

  • Page 8 The LT5 Gen-V engine feature oil-spray piston cooling, in which eight oil-spraying jets in the engine block drench the underside of each piston and the surrounding cylinder wall with an extra layer of cooling, friction-reducing oil. The oil spray reduces piston temperature, promoting extreme output and long-term durability.
  • Page 9 A worn or misaligned pilot bearing can cause shifting problems and rapid clutch wear. There are two different Chevrolet pilot bearings for the LT5, 14061685 is for a long input shaft transmission and 12557583 is for a short input shaft transmission.
  • Page 10 Charge Air Cooling System (LT5) This kit contains a charge air coolant pump. The pump is controlled by the Chevrolet Performance Parts engine control system. The charge air cooling systems function is to reduce the temperature of the air charge that is heated during the supercharging process which improves the efficiency and performance of the powertrain.
  • Page 11 Also, do not expose the engine to extended periods of high load. Change the oil and filter. Again, inspect the oil and oil filter for any foreign particles to ensure that the engine is functioning properly. 19417106 LT5 Dry Sump Engine Installation IR 03OC18 TITLE PART NO.
