This publication provides general information on components and procedures that may be useful when installing or 

servicing a ZZ502 deluxe assembly. 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, torque information, ZZ502 deluxe engine 

assembly specifications, engine start-up and break-in procedures, component information, and a service parts list.

 

The ZZ502 deluxe engine assembly includes additional components to the long block assembly which make up the deluxe 

engine. Additional key items include the intake manifold, carburetor, distributor, and the water pump.  The ZZ502 deluxe 

engine is a fully assembled engine. This engine is assembled using brand new, premium quality components. The ZZ502 

deluxe engine is manufactured on current production tooling; consequently you may encounter dissimilarities between 

the ZZ502 deluxe engine assembly and previous versions of the big block V8.  In general, items such as motor mounts, 

accessory drives, exhaust manifolds, etc. can be transferred to a ZZ502 deluxe engine when installed in a vehicle originally 

equipped with a big block V8 engine. However, as noted in the following sections, there may be significant differences 

in the water pump, torsional damper, etc., between a ZZ502 deluxe engine and an older big block V8 engine. These 

differences may require modifications or additional components not included with the ZZ502 deluxe engine. When installing 

the ZZ502 deluxe engine in a vehicle not originally equipped with a big block V8, it may be necessary to adapt or fabricate 

various components for the cooling, fuel, electrical, and exhaust systems. Due to the wide variety of vehicles in which a 

ZZ502 deluxe engine can be installed, some procedures and recommendations may not apply to specific applications.

 

Chevrolet recommends that you use a minimum octane rating of 92 (R+M/2) fuel in the ZZ502 (9.6:1 compression ratio) to 

prevent preignition.  It is not the intent of these specifications to replace the comprehensive and detailed service practices 

explained in the factory service manuals.
