Reference: Chevy Engine Block Casting Numbers

Beginning in the stamp included the serial number of the car it was installed in. The engine in my Corvette contains the following number sequences: FHE. Decoded, the first sequence is 6 for the year 66 and then the VIN sequence of The second stamp decodes F for the Flint Plant, May 18 is the engine assembly date and the HE suffix code stands for a ci hp with a manual transmission. So there you have the basics of decoding engine numbers for the purpose of documentation. Please note that there are some exceptions to the information contained above.

In it is said that there was a shortage of blocks from the Flint plant, so Chevrolet used some engine blocks from Tonawanda. Those engines would have a T instead of F on the stamp, as well as the full year in the cast date. There are several publications that contain a breakdown of engine codes and sequences. The NCRS also provides a publication that details how engines were stamped and therefore, may help you identify restamped engines. Having a piece from July would not work even though it looks accurate.

Thanks for the comments. I have read in various books that it is acceptable for an engine block to be cast as much as 6 months in advance of the assembly. I think like you that anything over one to two months is cause for a red flag with further investigation necessary. Particularly as you get later in the build year. Hi, I have a small block motor that a friend says is a Corvette motor because it has the spark plug wire holders on the side.

The O22 is Jan 2nd. The RC is HP. If you have looked very carefully and find no numbers there, chances are your block is classified as a Replacement Block and will have no numbers stamped on that deck.

Critical Warning System! In later years, the size of the engine was cast into the driver's side block skirt. This will also have the 8 digit casting number nearby. Thanks, hursst and NTX I'll look at the website. I'm hoping it's a '67, I understand this was the first year for the ? This is only a block, but it looks old. The pistons have valve reliefs. A source I read said that the partial vin should have an "8" for the '68 model year instead of a "7" for this sequence of numbers.

The came out in '67, but it was a Camaro exclusive for the SS Not sure what you mean about the partial VIN. Yours shows a 7, why would an 8 be mentioned or the '68 model year be mentioned when your VIN has a 7? Thanks, hursst. Ok, This engine has this code 17K, 9 characters and it looks like '67 or '77, but the pictures on the site I looked at showed a '67 having a code 7A 8 characters and '68's with codes 18K23? These having a resemblance to the code on this engine except for the second character being an 8.

The pistons have valve reliefs, would a '77 had come with these?

I did a little more research. Your block number , wasn't introduced until late April of , meaning it had to have been from There should also be a casting date on the block, which should be at the rear of the block to the right of the casting number. It should read something like M 3 7, Meaning Dec 3, , for your block. See if that is on the back of your block and that should answer the question about the date. Also, Chevrolet started painting their blocks "corporate blue" in , so if you have any blue paint left over on the block, then that's another give away.

Valve reliefs were common with certain Chev small blocks during the era, while others didn't have them.

Depends on the application. Hope this helps a little. I have no doubt it would be a model year motor, given the three letters at the end of the "machining code".

Historically, "valve reliefs" might have started in the earlier s, when camshaft lifts increased during the "high compression" era, BUT the piston in the Chevy was what I term "4 valve cut-out, dished and beveled" piston in them. This same configuration piston was also used in the Corvettes with aluminum cylinder heads smaller combustion chambers and 9. The small block casting was pretty much common in the s. Or if the main journals were the same size, a Different strokes would mean different piston "compression height" for a constant "deck height" or compression ratio in the engine.

I also believe it could be either a 2-bolt or 4-bolt main block, depending upon how the main cap machining and such were done? Remember, it's the "machining code" which defines what the engine was built to go in and what other items were attached to it to make the completed engine assembly "hanging on the hook at the assembly plant". The smaller stamp is which particular vehicle it resided in.

This will identify the piston as.
