How to understand Engine Identification Numbers

[earl35chev]

I went to the library and found engine identification number for Chev engine, however there is no explaination for the last three items other than, "type code".  My engine's last three items are WKA.  Does anyone know how to read this and what does it mean?  Thanks for your help.  I know the first "0" is the source code, second "00" is the month produced, the third "00" is the day produced, the real question is the fourth group "000" type code.  Thanks again. Earl

Hey Earl:

May I suggest a couple of websites for you to take a look at.

First Try this site,
http://www.nastyz28.com/chevy-engine-code-stampings.php

If the WKA is a suffix and you have a small block this is what I could come up with

RPO  FY     CID       appl      VIN     HP     BBLS      Body/Comments
WK 1969   350    tur hydro     -      255      4                C-10 to 35

The other site I would check is www.mortec.com

I think I may cofuse the issue but I also found this..

WKA sounds like the suffix code. If it is a small block V8 It should tell what the engine was installed in. I might have it listed...will check.

The man with the bad '58 beat me but I get a different result

WKA 1994 Impala 265 cu in 200HP SFI,  RPO L-99 TH700r4 transmission

accuracy of suffix codes can be dicey, depends on the source of the listing you use

DID YOU READ THAT, man with the "Bad 58", you are the first person to EVER say anything like that about me car, everyone else comes up to me and says... "WOW, what a neat car, my (INSERT FAMILY MEMBER DESCRIPTION HERE) had a car just like that"

No kidding, first time.... I LOVE YOU MAN!  :b-d: Come on down we can take the big BOAT for a KRUZ!

You can cross reference with the block casting number. on the right of the bell housing flange, behind the left head.

Hey, guys thanks for your help.  I have not seen the suffix code broken down in two parts before.  The engine is somewhere in the 94-95 year range.  It is a multi-port fuel injector engine.  I also saw the WK for the '69 year but I don't believe the multi-ports were back there.  Will keep looking and will check the casting numbers.  Earl

I went to a dealership and they were able to tell me what the WKA (suffix code) means.  It is a 4.3 vinW from a 1994 Caprice.  The vinW stands for a multiport engine if it was a vinZ it would be a throtal body engine.  Earl
