Chevrolet Performance 19370164 Manuel D'installation page 2

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.
This long block uses an engine control system based on a 24X crankshaft trigger and a 1X camshaft trigger system that was
used on Chevrolet Gen III small block V8 engines from 1997 thru 2006. For most customers this will be a replacement for an
existing application using a Gen III engine. This will allow the customer to transfer many of the sensors, exhaust system, engine
mounts, etc. from the current vehicle to this long block. This long block uses the higher flowing rectangular cylinder head intake
ports which were not available for Gen III engines. These heads were used on Gen IV LS3 engines. A new intake manifold will
be required from a Gen IV truck or car that used a rectangular intake port. Most 6.0-6.2 Liter Gen IV intake manifolds use this
type of rectangular intake port.
