283 Chevy Engine Serial Number Location

Small Block Chevy Engine Block Identification

General Decoding Information
This topic can be somewhat confusing, especially with the amount of information available and the interpretation of it. The primary pieces of information you'll decode are the Engine Code and Partial VIN. You can decode the casting number. And you can check dates. The engine code and partial vin # will accurately nail down whatever the thing is rather quickly, and the other information will fall into line with that.

Depending on the size of the engine, the location of the identification number will vary. Look for the identification number on the engine block. The identification numbers on a Chevy engine with a small block V-8 are adjacent to the cylinder heads on the passenger’s side, close to the front of the engine block.

This page has basic information on it, but it's a portion of the Small Block Chevy numbers information. The Engine Code page is where this topic is further detailed.

'Numbers Matching'
This is my opinion, and the generally accepted norm:
When people say 'It's numbers matching' - what they mean is the engine (or other component, i.e the transmission) can be MATCHED to the vehicle it was originally used in. This match is done via the PARTIAL VIN stamp on the component. The partial VIN will match the vehicles VIN. If it does - it's 'numbers matching', otherwise - it's not. done. end of story.
Some folks use these terms loosely, or will say 'numbers correct' or something to that effect. But numbers correct is not numbers matching. Again, it either matches or it doesn't. If it doesn't match - is it correct?
Numbers matching is important when you're trying to decode a Z28 or Super Sport where the VIN won't identify the vehicle as such. You need to decode the engine and see if it matches the vehicle, and if the code signifies Z28 or SS equipment.
Lastly, in extreme cases, you'll want to verify the numbers stamped onto the component were the ones stamped into it originally and aren't restamped.
The point of this article is to help you figure out how to decode stuff.

In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stamped next to, or under the engine code ID. Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the block pad (in front of the cylinder head), or on the transmission flange somewhere. According to my Chilton manual, an 'E' suffix is for a 1957 model passenger car 283. Check the bore size-a 265 should have a 3 3/4' bore, while 283's were 3 7/8'. Also, a 55 model 265 will NOT have a block-mounted oil filter; they used the same remote filter as the 235's. The first V-8 with a block-mounted full flow filter was the 56. In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stamped next to, or under the engine code ID. Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the block pad (in front of the cylinder head), or on the transmission flange somewhere. Chevrolet issued technical service. Pre - 1953 Chevrolet Engine Serial Number Location: Engine Serial Number is Located on the right side of the engine on a boss just to the rear of the ignition distributor for 216 and 235 c.i. Inline 6 cylinder engines.

Engine Code Stamping Numbers
All engines are stamped with an engine ID code, consisting of assembly plant code, production date and suffix code. V8 codes are stamped on a pad just forward of the right side (passenger) cylinder head. 6 cylinder engines are stamped on the passenger side of the block behind the distributor.

The engine date must precede the car build date, otherwise something is amiss. Some engine machining operations (decking) will obliterate the engine ID.

Engine ID Code Example: V0101CLJ - (V = Plant, 01 = Month, 01 = Day, CLJ = Engine Suffix Code)
Another example: T0830CTY - (T = Tonawanda, 08 = August, 30 = 30th day, CTY = 1970 396 Camaro, 375 hp, 11.0:1, TH400)

F	Flint (Motor)	S	Saginaw Service
H	Hydramatic	T	Tonawanda
K	St. Catherines, Ontario	V	Flint (Engine)

VIN Code Format
The vin code format is stamped onto most engines. The format consists of divisional identification number, model year, assembly plant designation and vehicle serial or sequence number.
In 68-69 model cars, the serial (VIN) number of the car the engine was installed in is stamped next to, or under the engine code ID.
Starting in 1970, the serial number is stamped either above the oil filter, somewhere on the block pad (in front of the cylinder head), or on the transmission flange somewhere. Chevrolet issued technical service bulletins to indicate which engines were to recieve a vin stamp, so who knows what could have happend (or not happened).

VIN code format Example: 13N100001
(1 = Chevrolet, 3 = 1973, N = Norwood, 100001 = Production sequence of vehicle VIN)

Casting Clock

283 Chevy Engine Serial Number Location 1948 Ford F1 Pickup

On some Saginaw blocks, intakes and exhausts a 'clock' was cast into the block. The clock is a circle of 10 dots, one dot for each hour of a shift (usually 10 hour shifts). An arrow points to the beginning of the shift an another dot outside the circle indicates what time of day the cast part was made. Anyways, that's what that circle thing is (if you happen to see it on something). Casting Date
Small block casting date is located on driver side rear of block on flange forward of bellhousing. Big block on the right side of engine above the oil pan rails.

Casting Date Example: E038 - (E = Month, 03 = Day, 8 = Last digit of model year (1978)).

Month: A = Jan, B = Feb, C = Mar, D = Apr, E = May, F = Jun, G = July, H = Aug, I = Sep, J = Oct, K = Nov, L = Dec

General Engine Block Specifications
While 6 different bore size blocks have been produced, the small block engine can be classified into 3 bore sizes and 3 main bearing sizes. 283 blocks (3.875' bore, 2.3' main), 302/327/350 blocks (4' bore, 2.3' or 2.45' mains), and 400 blocks (4.126', 2.65' mains). In 1968 the main bearing saddles were increased in size from 2.3' to 2.45'.

Notes: 2 bolt ONLY means just that,. otherwise 2 or 4 bolt can mean either design...

Chevy Small Block - Engine Block Casting Numbers

Notes (for below): 'High Power' is the maximum rate HP this block was used for, 'Low Power' is the lowest rated horsepower RPO engine the block was used in. 'Main Caps' is the number of bolts holding the cap. A 'two-bolt' main, or a four-bolt main. Four bolt main blocks are desirable in high performance applications because the extra strength of the additional bolts keeps the bottom end rigid and less prone to failure. However, a properly prepared 2 bolt main engine will work just fine (often times you'll lose a rod bolt before you break a crank because it's 'only' a 2 bolt main).
