The Stovebolt Site Forums The Shop Area Engine Shop Your model of chevy 230 engine?

Could someone tell me what year model my 230 engine. I was tolled it was a 1967 CL9601592. That was the number right by the distributor. The distributor is a HEI. Thank you for your help.

Last year for 230 was '65. HEI was not in widespread use at GM until 1975.

This is a NOVA site, so it may not be accurate for a pickup engine, but worth a look anyway. http://www.novaresource.org/codes.htm
HEI is a later distributor, but a good one to have. The heads for the inlines were all the same with a few different part numbers for the 230-250-292 engines, so don't go by them, same for the block casting numbers, 230 and 250 used the same blocks, just different cranks and pistons. You can make a 230 into a 250 with the right parts. Best way to tell the difference is the piston tops, 250 is dished, 230 flat, 250 has a longer stroke also.

Asahi1234,

You have asked this question in a number of previous posts ( HERE and HERE ).

Much information was previously provided to help identify your "230" engine. If you go back and look at the replies in there, the only definite info that could be provided (based on the casting#) is that it is a 230 made between 1963-1970. The date casting code "E2769" would likely indicate manufactured May 27 1969, but that can't be confirmed as the casting also indicates it was "Hecho En Mexico" (Made in Mexico) and I can't confirm any info on blocks cast in Mexico. Others have mentioned the fact that they were unaware these engines where being manufactured in Mexico during that time period. Perhaps it's a replacement block???

The engine serial number prefix "CL" is not listed in any GM Heritage data that I could determine, so no help in confirming. FWIW, the HEI distributor was probably used to replace an original points style distributor at some point by a previous owner, so that is also no more help in identifying your engine.

Bottom line is if you are needing to get the engine rebuilt, based on previous discussions, you need to take it to a qualified engine shop that can properly measure it and help you get the parts you need for the rebuild. Good luck on your build.

BTW - What truck are you planning on installing this engine in??? How about some pictures???

Thank you very much. Sorry forgot about previous post. My memory is not good as it used to be.
