The ZZ454/440 base engine is a fully assembled long block. This engine is assembled using brand new, premium

quality components. The ZZ454/440 engine is manufactured on current production tooling; consequently you may

encounter dissimilarities between the ZZ454/440 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 ZZ454/440

engine when installed in a vehicle originally equipped with a big block V8 engine. However, as noted in the following

sections, there may be signicant differences in the water pump, torsional damper, etc., between a ZZ454/440 engine

and an older big block V8 engine. These differences may require modications or additional components not included

with the ZZ454/440 engine. When installing the ZZ454/440 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 ZZ454/440 engine can be installed, some procedures and

recommendations may not apply to specic applications.

It is not the intent of these specications to replace the comprehensive and detailed service practices explained in the

GM service manuals.

For information about warranty coverage, please contact your local Chevrolet Performance Parts dealer.

Observe all safety precautions and warnings in the service manuals when installing a ZZ454/440 engine in any vehicle.

Wear eye protection and appropriate protective clothing. Support the vehicle securely with jackstands when working

under or around it. Use only the proper tools. Exercise extreme caution when working with ammable, 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.

Caution

This engine assembly needs to be lled with oil and primed. You should add the specied oil (see start-up instructions) to your

new engine. Check the engine oil level on the dipstick and add accordingly.

Start-up and Break-in Procedures

1. After installing the engine, ensure the crankcase has been lled with 5W30 motor oil (non-synthetic) to the recommended

oil ll level on the dipstick. Also check and ll as required any other necessary uids such as coolant, power steering uid,

etc.

2. The engine should be primed with oil prior to starting. Follow the instructions enclosed with the tool. To prime the engine,

rst remove the distributor to allow access to the oil pump drive shaft. Note the position of the distributor before removal.

Install the oil priming tool. Using a 1/2" dill motor, rotate the engine oil priming tool clockwise for three minutes. While you

are priming the engine, have someone else rotate the crankshaft clockwise to supply oil throughout the engine and to all

the bearing surfaces before the engine is initially started. This is the sure way to get oil to the bearings before you start the

engine for the rst time. Also, prime the engine if it sits for extended periods of time. Reinstall the distributor in the same

orientation as it was removed.

3. Safety rst. If the vehicle is on the ground, be sure the emergency brake is set, the wheels are chocked and the car cannot

fall into gear. Verify everything is installed properly and nothing was missed.

4. Start the engine and adjust the initial timing. If using the HEI distributor P/N 93440806, set the ignition timing to 4º before

top dead center (BTDC) at 650 rpm with the vacuum advance line to the distributor disconnected and plugged. This

setting will produce 26º of total advance at wide-open throttle (WOT) when using the HEI distributor P/N 93440806. The

HEI vacuum advance canister should remain disconnected. This engine is designed to operate using only the internal

centrifugal advance to achieve the correct timing curve. Rotate the distributor counterclockwise to advance the timing.

Rotate the distributor clockwise to retard the timing.

5. When possible, you should always allow the engine to warm up prior to driving. It is a good practice to allow the oil sump

and water temperature to reach 180°F before towing heavy loads or performing hard acceleration runs.

6. Once the engine is warm, Double check the total advance timing is 26° at 4000 RPM if using the HEI distributor P/N

93440806.

7. The engine should be driven at varying loads and conditions for the rst 30 miles or one hour without wide open throttle

(WOT) or sustained high RPM accelerations.

8. Run ve or six medium throttle (50%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.

9. Run two or three hard throttle (WOT 100%) accelerations to about 4000 RPM and back to idle (0% throttle) in gear.

10. Change the oil and lter. Replace with 5W30 motor oil (not synthetic) and a PF1218 AC Delco oil lter. Inspect the oil and

the oil lter for any foreign particles to ensure that the engine is functioning properly.

11. Drive the next 500 miles under normal conditions or 12 to 15 engine hours. Do not run the engine at its maximum rated

engine speed. Also, do not expose the engine to extended periods of high load.

12. Change the oil and lter. Again, inspect the oil and oil lter for any foreign particles to ensure that the engine is functioning

properly.

13. Do not use synthetic oil for break-in. It would be suitable to use synthetic motor oil after the second recommended oil

change and mileage accumulation. In colder regions, a lower viscosity oil may be required for better ow characteristics.

Information may vary with application. All specications listed are based on the latest production information available at the time of

printing.

Additional parts that may be needed:

Flywheel / Flexplate:

Like all big block V8 engines, the ZZ454/440 engine has 3.58" diameter ywheel ange bolt pattern. This engine comes equipped

with a 14" diameter explate with a 168 tooth ring gear, GM Part Number 10185034. If your application requires a ywheel, GM Part

Number 14096987, should be used. This ywheel is 14" diameter, 168 tooth ring gear, and is a for 11" diameter clutch. Use ywheel

bolt GM Part Number 12337973 (6 required).

Pilot Bearing:

You must install a pilot bearing in the rear of the crankshaft if the engine will be used with a manual transmission. The pilot bearing

aligns the transmission input shaft with the crankshaft centerline. A worn or misaligned pilot bearing can cause shifting problems and

rapid clutch wear. A roller pilot bearing, GM Part Number 14061685, is recommended for this engine. This heavy-duty bearing adds an

extra margin of reliability to a high performance drivetrain.

Oil Pan:

The ZZ454/440 engine includes oil pan, GM Part Number 10240721. This six-quart pan was originally designed for marine and truck

usage and may cause interference problems when installed in certain applications. Check for clearance before installation of the

engine. If the six-quart pan will not t into your application, GM Part Number 12495360 is recommended as a substitute. This is a four-

quart, right-hand dipstick oil pan, which comes with the gasket, four main cap bolts, oil pump screen, dipstick and tube.

Headers:

A ZZ454/440 engine should be equipped with a header exhaust system for maximum performance in applications where a non-

production exhaust system is legal. For street performance and limited competition applications, the recommended header

conguration is 2" diameter primary pipes, 36 inches long, with 3 1/2" diameter collectors. Use 3" diameter tailpipes with a balance tube

(“H” pipe) and low restriction mufers.

Rocker Covers:

The ZZ454/440 engine comes equipped with die cast rocker covers, GM Part Numbers 12553666 and 12553667. Additional tall and

short valve covers are available. Please see the website at www.chevroletperformanceparts.com or your local Chevrolet Performance

Parts dealer. When using either the cast aluminum or the tall, chrome rocker covers; ensure that enough clearance exists between the

cover and the brake booster.

Le moteur standard ZZ454/440 est un moteur à bloc long entièrement assemblé. Ce moteur est monté au moyen

de composants neufs de première qualité. Le moteur ZZ454/440 est fabriqué sur l'outillage de production actuel.

Par conséquent, il est possible de rencontrer des dissemblances entre le moteur ZZ454/440 et les précédentes

versions du gros bloc V8. En général, les éléments tels que les xations du moteur, les entraînements d'accessoires,

les collecteurs d'échappement, etc. peuvent être transférés sur un moteur ZZ454/440 lorsqu'ils sont montés sur un

véhicule équipé à l'origine d'un moteur V8 gros bloc. Toutefois, comme il est indiqué dans les sections suivantes,

il pourrait y avoir des différences importantes au niveau de la pompe à eau, de l'amortisseur de torsion, etc., entre un

moteur ZZ454/440 et un moteur V8 à gros bloc plus ancien. Ces différences peuvent nécessiter des modications ou

des composants supplémentaires non compris avec le moteur ZZ454/440. Lors du montage d'un moteur ZZ454/440

sur un véhicule non équipé à l'origine d'un V8 à gros bloc, il peut être nécessaire d'adapter ou de fabriquer divers

composants pour les systèmes de refroidissement, d'alimentation en carburant, électriques et d'échappement.

En raison du grand nombre de véhicules sur lesquels le moteur ZZ454/440 peut être monté, certaines procédures

et recommandations peuvent ne pas s'appliquer aux applications particulières.

Ces caractéristiques techniques ne sont pas destinées à remplacer les pratiques d'entretien complètes et détaillées

expliquées dans les manuels d'atelier GM.

Pour obtenir de l'information sur l'étendue de la garantie, prière de communiquer avec le concessionnaire

Chevrolet Performance Parts local.

la pose d'un moteur ZZ454/440. Ces renseignements ne sont pas destinés à remplacer les manuels de

réparation complets et les catalogues de pièces en matière de moteurs et de composants de la General Motors.

Plutôt, ce guide a été conçu pour offrir des renseignements supplémentaires sur les matières pouvant intéresser

les « bricoleurs » et les mécaniciens.

Cette publication s'applique aux moteurs et aux véhicules qui sont utilisés hors des voies publiques, sauf

indication contraire expresse. Les règlements fédéraux restreignent la dépose des véhicules automobiles

de toute partie d'un système antipollution exigé par la loi fédérale. En outre, de nombreux États ont établi

des lois qui interdisent le traquage ou la modication de tout système antipollution ou antibruit exigé par la loi.

En règle générale, les véhicules qui ne roulent pas sur les voies publiques, tout comme certains véhicules

d'intérêt spécial et pré-émissions, sont exempts de la plupart de la réglementation. On suggère fortement

au lecteur de consulter tous les règlements municipaux et provinciaux applicables.

Plusieurs des pièces qui sont décrites ou énumérées dans le présent ouvrage sont commercialisées à des ns

hors autoroute seulement et elles portent l'étiquette « Special Parts Notice » (avis sur les pièces spéciales) qui

est reproduite ici.

Avis spécial sur les pièces

Cette pièce a été conçue spéciquement pour une application hors route seulement. Puisque la pose de cette

pièce pourrait nuire au rendement antipollution du véhicule ou donner lieu à son manque d'homologation

en vertu des normes de sécurité actuelles des véhicules automobiles, celle-ci ne doit pas être posée dans

un véhicule qui sera utilisé sur une voie publique ou une autoroute. En outre, une telle application pourrait

donner lieu à l'annulation de la garantie d'un tel véhicule sur route ou autoroute.

Chevrolet, Chevy, l'emblème Chevrolet, General Motors et GM sont des marques déposées de General Motors.

Renseignements sur les composants :

Culasses :

Le moteur ZZ454/440 possèdent des culasses entièrement assemblées, numéro de pièce GM 12363392. Ces culasses,

à orice ovale, en aluminium, sont dotées de chambres de combustion de 110 cc, des soupapes d'admission en acier

inoxydable de 2,19 pouces et des soupapes d'échappement en acier inoxydable de 1,88 pouce.

Pose de la culasse :

La pose est semblable à celle des culasses d'origine. S’assurer de nettoyer la surface du bloc à fond, ainsi que la surface

de la culasse préalablement à la pose. Appliquer du Téon liquide sur tous les boulons à tête qui font saillie dans les conduits

de refroidissement. Serrer les boulons en alternance selon la séquence et la conguration illustrées ci-dessous. Serrer en

incréments de 25 pi-lb à deux reprises, puis serrer à nouveau jusqu’à la valeur de serrage ultime. Il est conseillé de resserrer

les boulons de la culasse suite au cycle de chauffe du moteur.
