Suffix & Casting #'s Codes question
 

Newbie here, I am trying to better get to know what is in my 68 C10. I know what you all are thinking at this moment whats this guy doing here, well so far what I have found out about the engine its a Firebird engine or it was the engine that was in use for the Firebirds that year and surprisingly it looks just like any Small Block Chevy engine. Here's the block casting #'s 14093627 so far what I have found out its from 87-94 & the driver side head #'s are 14014416 form 80-99. BUT here is the kicker the Suffix code is V0221AKA that's right the AKA is not a typo. This is whats stumping me being I know that GM engines with the AKA is a Big Block. What also I have found out is some of that years engines (87-94) have Suffix Codes as AKH or AKJ & ATA. What did I get myself into when i bought my Truck. I figured that going to a Third Gen F Body forums site would give me the best shot in getting some answers. Thanks in advance for any help. Marvin

According to NastyZ28 site, that casting number is a 305 cid small block. I wouldn't worry about the stamped numbers, it's the casting number that tells you what you need to know. The stamping will tell you what model car it was used in and what transmission was used with it. That doesn't matter anymore as that is not the car and transmission it is mated to. HTH!
As a side note, there are many members here that never have or don't anymore, own a thirdgen but gain and pass along knowledge just the same. You won't get torched too bad! HaHa! Sounds like a nice truck. Search around the site, it is amazing the amount of knowledge on these forums. GL!

I know the 305's aren't nothing to write home about but that's what was in the truck when I bought it and it does run pretty good so it will stay for now. Where is a date Code on the 305 engine located? This might give me a better knowledge on the engines year. My truck before & after getting rid of the "wagon wheels" LOL

Re: Suffix & Casting #'s Codes question
 

V0221AKA - V = Flint plant, 02 = Feb., 21 = day of month. To find the year, you need the casting date of the block which is on the rear drivers side of the block. Goto NastyZ28.com for a load of info on casting codes. There is another site, Mortec.com, that has a lot of info also. And, btw, there is absolutely nothing wrong with the 305 in your truck. They are very good engines, as witnessed by their longevity, just not the best for a performance build. I do like the "new" wheels, very cool!

Re: Suffix & Casting #'s Codes question
 

The AKA kinda through me since the "AKA" belongs to the Big block family not the Small blocks. The engine is still in the Truck so a little hard to see the Date code numbers, does any one Know the *Exact location*of the date code? **Like for instance 1" from what ares to or from 2" from that spot (wheres it exactly).
