This publication provides general information on components and procedures which may be useful when installing
or servicing an HT383E engine. Please read this entire publication before starting work. Also, please verify that all
of the components listed in the Package Contents section below were shipped in the kit.
The information below is divided into the following sections: package contents, component information, HT383E
engine specifications, additional parts that you may need to purchase, torque specifications, and a service parts
list.
The HT383E engine incorporates modern technology in a package that can be installed in applications where
265-400ci small block Chevrolet V-8's were originally used. This complete engine is assembled using brand new,
premium quality components. Due to the wide variety of vehicles in which an HT383E engine can be installed,
some procedures and recommendations may not apply to specific applications.
The HT383E engine consists of a cast iron engine block, cast iron cylinder head assemblies, forged steel
crankshaft, hypereutectic pistons, forged powder metal connecting rods, and a performance camshaft.
The HT383E engine is manufactured on current production tooling; consequently you may encounter
dissimilarities between the HT383E engine assembly and previous versions of the small block V-8. In general,
items such as motor mounts, accessory drives, exhaust manifolds, etc. can be transferred to an HT383E when
it is installed in a vehicle originally equipped with a small block V-8 engine. However, as noted in the following
sections, there may be minor differences between an HT383E engine and an older small block V-8 engine. These
differences may require modifications or additional components not included with the HT383E engine. When
installing an HT383E engine in a vehicle not originally equipped with a small block V-8, it may be necessary to
adapt or fabricate various components for the cooling, fuel, electrical, and exhaust systems.
It is not the intent of these specifications to replace the comprehensive and detailed service practices explained in
the Chevrolet service manuals.
