Additional parts that may be needed:
Flywheel / Flexplate:
Like all small block V-8 engines produced since 1986, the ZZ383 engine has a 3.00" diameter flywheel flange bolt pattern. Small
block V-8 engines produced from 1958 through 1985 had a 3.58" diameter flywheel flange bolt pattern. This change in bolt circle
diameter was made to accommodate a leak-resistant one-piece rear main seal. This ZZ383 engine includes a 12 3/4" diameter
flexplate part number 14088765. A manual transmission flywheel is available (part number 14088650). See the catalog or visit
www.chevroletperformance.com
NOTE: You must use a 14" diameter flexplate if using Chevrolet Supermatic torque converter.
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, part number 14061685, is recommended for this engine. This heavy-duty
bearing adds an extra margin of reliability to a high performance drivetrain.
Starter:
This ZZ383 engine does not include a starter. The starter must be matched to the flywheel or flexplate diameter when installing
the ZZ383 engine. Small diameter flywheels are 12-3/4" in diameter and have a starter ring gear with 153 teeth. Large diameter
flywheels are 14" in diameter and have 168 teeth on the starter ring gear. This difference in flywheel diameters requires two
different starter housing. Starter noses used with 14" diameter flywheel have two offset bolt holes; starters used with 12-3/4"
diameter flywheels have bolt holes that are straight across from each other.
Note: Chevrolet starter motors use special shouldered mounting bolts which register the starter on the block.

Carburetor/Air cleaner:
A 750 or 770 cfm four-barrel carburetor with vacuum operated secondaries and electric choke is recommended for the ZZ383
engine. Chevrolet Performance recommends using the Holley 770 cfm four barrel carburetor p/n 19170093 to make the most
of the engine's capability and achieve the listed horsepower and torque ratings. A foam or paper element, low restriction air
cleaner should be used to protect the engine from excessive wear and diffuse the air entering the carburetor. The fuel mixture
distribution can be upset if no diffuser is used causing poor power and misfiring at high engine speeds. Always check for
adequate hood clearance when installing a new air cleaner. Chevrolet Performance Parts has two chromed, 14-inch diameter,
open element air cleaner assemblies for single four-barrel carburetors. Part number 141-306 available from our licensed
partner
