V0223CCC its the number stamped on the front pass side head next 2 water pump.. not the casting number on the back of the block

 

Very little.

It's not a casting number, it's a stamping. It is the engine code that tells what chassis it came in, which changes year from year; you can look it up if you know what year it came from, or guess at what it might have been if you don't, by finding candidates in the database that aren't ruled out by obvious inconsistencies (wrong number of cylinders, etc.).

All in all, not good for much.

The numbers right below that are the VIN of the vehicle it was installed in. If they match your VIN, then it's the block (NOT the motor, necessarily) that came in your car; or someone stamped the right numbers back when they changed your motor out.

The one on the back of the block is acutallu useful, the one on the front is of very limited value.

 

yeah i just wanted to verify what chassis it came in, i know it doesnt match my car.. the actual casting number was only able to tell me its a 69 350 4 bolt main engine that was used in a high proformance application, i was told that it was pulled from an old police interceptor just wanted to see if i could verify that, also i can sorta see the vin number but the block has a nice fresh coat of paint and it fills it some of the numbers making it hard to read...

 

What's the casting # and date?

 

0223 is a date code meaning February 23rd.

sounds like a 1971 2bbl 200HP 307 to me

Im positive its a 4 bolt main 350 though do to the bore stroke and the fact that it has 4 bolt mains... otherwise i dunno how i got the pistons in it i'll post the casting numbers n date code tomorrow. have em on a piece o paper but i cant find it so i'll just try to gettem off the block 2morrow.. the c's in the other 1 could possibly be capital D's,O's, or G's i cant really tell due to the paint im pretty sure of the numbers though

 

How do you know it has 4-bolt mains? You can't tell that from outside the oil pan. The casting number won't tell you, and even the application stamp isn't always a certain indicator, although if it shows to have been in a truck, it's pretty likely to have been fitted with the 4-bolt caps.

What's the casting number? That's the single most useful piece of info you can get from outside the engine; it will tell you what the bore is at least. The casting date code will also give you a clue what year car it probably came in.

 

due 2 the 4 bolts on the middle 2 bearings.. i bought the block bare had it bored 30 over and assembled it.. i was just curious as to what it was origionally in, i know it really doesnt mean anything since its just a block and has none of the origional internals or anything but i was just curious

 

k got some numbers, cant see the date code cause theres too much crap in the way, the number off the front is VO223CGC not CCC, and the casting number is 3970010.. it has 28GM in front of it sorta if it means anything...

 

Real hard to say... that was a very popular casting number from the introduction of the 350 up until they moved the oil dipstick; it came in everything from full-size cars to Camaros to trucks, but especially trucks. Probably ¾ of that # or more that I have ever seen in their native home, were in trucks. I had a 78 Z28 and a 79 Z28 with pig 2-bolt 180 HP 350s that used it too, and I built motors for people's trucks, I can recall a 74, a 76, and a 79 that had it. Those were even worse from a performance standpoint than the Z28s, but at least the truck blocks had been fitted with the 4-bolt caps, which the Z28s had not.

There will be a date code near the casting #; it will look something like 2B14. That example would be the 14th day of the Bth month of a year ending in 2, or Feb 14, 19x2. Knowing what casting it is, you can guess what decade it was made in; so if yours said that, it would have been cast in Feb 72, probably went into a 73 model vehicle, probably a truck.

Somebody with a reference to those stamping codes might be able to tell you more about its original vehicle. It's not something that really makes any kind of actual difference when building one, so I pay them no mind. They are altogether useless unless you're trying to build a "numbers matching" show car.

 

The suffix code book I have here at work lists it as a 1971-72 350. 2 OR 4 bolt.

Common apps were El Camino, Impala, Wagon etc.





HTH

 

yup sounds about right.. it was supposedly pulled from an old police car so that would make sense.. i know it really doesnt make a difference at all what it came in or anything since it was just a bare block with no internals but i was just curious
