Introduction

AERA gratefully acknowledges the excellent cooperation and feedback provided by all Past, Active and Associate members who were called upon for assistance in the creation of this manual.

This manual is created from latest information contained and maintained in PRO-SIS AERA's Engine Specification Software program. All information contained in the manual is available on a CD-ROM for use in your shop. PRO-SIS also links these specifications with applicable AERA Technical Bulletins for easy review of the latest product updates and revisions.

The word PRO-SIS stands for Professional Specification Information Software.

Machinists Shop Data

Identifying A Cylinder Head Or Block - When the identity of a head or block is not known, it is best to first attempt to locate an identifying number or mark.

A casting number is usually stamped or cast into the cylinder head or block. All casting numbers known to AERA have been listed in this manual.

Many cylinder heads or blocks do not carry a casting number. OEM has been known to use the same head or block in different applications. Identification may be possible from insignias, paint marks or other markings located on the cylinder head or block. Try to I.D. heads and blocks before cleaning, as any painted marks will be removed. Reference the comments in the Alphabetical Listing By Manufacturer section of the manual for these marks.

Locating Specifications By Casting Number - Find the casting number in the numerical list of casting numbers. Known casting numbers for cylinder heads may be found in the cylinder head section. Similarly, cylinder block casting numbers may be found in the cylinder block section of this manual. The corresponding engine manufacturer, displacement(s), and specifications are detailed in the alphabetical listing section.

An asterisk (*) or it may be (**) or more indicates that additional information about the cylinder head or block can be found under comments.

Locating Specifications By Manufacturer ? Engines are listed by; Make, cubic inch, Liter from smallest to largest. The number of cylinders is at the beginning of each section in the alphabetical listing section (i.e., four cylinder, six cylinder, eight cylinder, etc.). Note that extensive use of VIN codes has been made to insure that the proper specifications are listed.

Multiple VIN listings: Vehicle manufactures use the same VIN designation character for different engines, (i. e. GM uses 1.6L VIN 6) these engines that are manufactured by four different engine companies, Daewoo, Isuzu, Suzuki & Toyota. Others such as the Ford 5.0L VIN F have seven different records according to years used.

Those different records are necessary as engine specifications or castings changed significantly enough to warrant a different record.

Engine And/Or Equipment Specifications

Since many vehicle manufacturers will offer engines of other than their own manufacture, it may be necessary to refer to another section in the manual (i.e., Saturn- see GM, Lincoln, Mercury - see Ford Motor Company).

Year Produced and/or Used - when this data is applicable this column shows the production year, or years, when the engine is or was made and/or used by the manufacturer.

The year(s) data is also used to indicate variations in model years when an engine is, or was, used in differently named vehicles and/or equipment.

New Height - OE manufacturer's production cylinder head height (thickness)

Minimum Height - minimum recommended cylinder head height (thickness).

Intake Height - The installed intake valve stem height, the distance between the tip of the valve and the valve spring seat, is listed in this column. Where applicable the valve's recession or protrusion specification in relationship to the cylinder head deck surface is listed. * If a different procedure for measuring is needed it will be noted.

Exhaust Height - The installed exhaust valve stem height, the distance between the tip of the valve and the valve spring seat, is listed in this column. Where applicable the valve's recession or protrusion specification in relationship to the cylinder head deck surface is listed. * If a different procedure for measuring is needed it will be noted.

Intake Protrusion /Recession - The location of the intake valve head in relationship to the cylinder head deck surface. Protrusion (+) signifies that the valve is located above the deck surface. Recession (-) signifies that the valve is located below the deck surface.

Exhaust Protrusion / Recession - The location of the exhaust valve head in relationship to the cylinder head deck surface. Protrusion (+) signifies that the valve is located above the deck surface. Recession (-) signifies that the valve is located below the deck surface.

Head # - Cylinder head casting numbers.

Block # - Cylinder block casting numbers.

Variations in production practices, foundry sources and OEM running changes are quite common and it must not be assumed, nor guaranteed, that a casting number as listed is complete for all models shown. Do not attempt to use this manual as an interchange manual.

Some casting numbers may be extended by open spacing or other separating methods such as dots, dashes, etc. It is important to locate the complete number. In some General Motors cylinder heads or blocks, only the last significant digits are listed in the manual, whereas the component may show the same digits preceded by other markings or numbers.

Notes - Additional information about the cylinder head or block.

Comments - This last line of each listing may contain additional information about this engine.

Cylinder Head Measurements

New and Minimum cylinder head heights are checked as above. When measuring head thickness it must be between two machined surfaces. Some cylinder heads are measured from a head bolt boss down to the deck surface. Although bolt boss measurement was correct for years, AERA members have reported that the OEM head bolt bosses have not remained a constant dimension. New cylinder heads like the GM NorthStar are measured from the deck surface to a gauge pad in combustion chamber. When you have a cylinder head height that does not measure correctly, you might have to check the combustion chamber volume. Filling up the combustion chamber and making sure the CC volume is correct for the engine you are working on.

Checking installed valve stem tip height. Checking installed valve stem tip height measuring down to cylinder head spring seat. Note: Some times the spring seat, valve spring shim or valve seal with spring shim built onto it must be used when checking it will be noted.

Quick Cubic Inch Displacement

.7854 X bore diameter X bore diameter X crankshaft stroke = cubic inches of one cylinder. .7854 X 4.00 = 3.1416 X 4.00 = 12.57 X 3.484 = 43.79 cubic inches of one cylinder. One cylinder containing 43.79 cubic inches X number of cylinders 8 = 350.32

Quick Check Engine Compression Ratios

The calculation of an engine's compression ratio (C.R.) is based on the formula:

SV + CV CR = --------------

CV

S.V. = =

Swept Volume for one cylinder in cc's. Bore X Bore X Stroke X 12.9

C.V. = =

Clearance Volume for one cylinder in cc's. H.V. minus E.D.V. plus D.V. plus G.V.

H.V. = =

Head Volume (published or measured in cc's) Best if measured because head volume varies.

E.D.V. = =

Effective Dome Volume (published or measured in cc's) Dome Volume minus valve relief and/or dish volume

D.V. = =

Deck Volume clearance (piston to deck) in cc's Bore X Bore X deck height X 12.9

G.V. = =

Gasket Volume in cc's

Gasket bore X gasket bore X compressed thickness X 12.9 or enter known gasket volume.

All compression volume measurements are in cubic centimeters. (cc's)
