You have a 350 block, therefore most likely a 350, and 350 TBI heads. FORGET trying to extract useful information from the stamping code. You have an engine made out of a 350 block that maybe came from such a car it happens to have heads on it that COULD HAVE come in such a car also, BUT the left one might have come from a 88 Blazer and the right from a 93 Buick and the Lord only knows what cam might be in it and what pistons somebody jammed into it. Once you know the bore of the block, you can then look at the piston configuration (flat-top, dome, dish, etc.), the heads, the cam, and so forth, and make an educated guess about what sort of engine you have.īut in a case like yours, the likelihood that the block stamping is going to tell you that the engine came out of a 95 Caprice, green with tan interior and steel wheels with AM/FM/CD radio and automatic climate control, is FANTASY LAND. Which of course the stamping code wouldn't tell you EITHER. For example it is extremely rare that someone would build anything but a 350 out of a modern 4" bore block, although it's possible that somebody might have put a longer-stroke crank in it and made a 383 engine out of it. and from there you can figure out what the CID is most likely to be. The block casting number (NOT stamping code) will however tell you what bore size the block is 3.736", 4.000", 4.125", etc. Since virtually NO engine that's swapped into a car, above all NOT a "rebuilt" SBC in a situation like you have, will contain the internal and external parts that came in it from the factory in totally unmodified form which turned the block into an engine, looking up the stamping on the block WILL NOT tell you what engine you have. Just like you can take the block from a 70½ Z/28 LT-1, and put TBI or terrible smogger heads on it and some peanut cam, and come up with a 180 HP POS engine complete with the romantic-looking block stamping complete with VIN. You can take the block from a 76 Impala 2-bbl, complete with the stamping that "decodes" to 155 HP or whatever take off the heads, intake & carb, pull out the cam & pistons, and replace them with racing grade parts and have a 500 HP engine as the result. See post #8 above, about conflating the identification numbers stamped on a block, with being able to tell anything about the engine built out of that block. I have read this can be a truck or car block. There is nothing wrong with it and it runs great. 14102193įuel Delivery / Fuel Injection Type: Throttle Body Fuel Injection (TBI) Funny thing the engine is TPI with TBI heads. The VIN shows 350 TBI which I though they didn't make in 89. On the engine its stamped V0326SAF which I cannot find the SAF listed. One the block is it stamped 638 near the plug. Its a 350 Roller engine with 5.7LG SGI on the back. I am searching the numbers to verify what it is. I have a 89 IROC that had a rebuilt engine when I purchased the car. There may not be a good answer other than its a 350 roller engine with the wrong heads. I added this question to a few thread hoping somebody knows. This is an old thread but I have questions about my engine. I was unable to find the casting number on the block. I did not get a picture of the date code and engine suffix, though it was in VERY good condition and I am pretty sure it is right (99% sure). I tried to get a picture of the "C88506" code I found, but it came out blurry because my camera sucks at up close pictures. I cannot find the suffix "8AN" anywhere though.Īttached is pictures of the block. I figure the engine was from Flint, and was cast on May 2nd. Only problem is, I cannot find anything about these codes. I also found the (I hope) date code with engine code suffix (V05028AN). I found the "GM 5.7LG SGI" stamp, and I found a number on the front of the block (passenger side), but it is very hard to read (looks like C88506). There is a lot of rust/wear on the block, but I was able to find a few things. Now I am trying to figure out everything I can about it to make sure I want to use it. I got it for very cheap so I grabbed it up. I bought a 350 block that was claimed to be from an '86 vehicle.
