Small Block Chevy Engine Block Identification


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".

CID Year Bore Main Cap
(NNN) NNN-NNNN3.671 2 bolt ONLY (NNN) NNN-NNNN- 81 3.500 2 bolt ONLY (NNN) NNN-NNNN- 96 3.736 2 bolt ONLY (NNN) NNN-NNNN- 73 3.875 2 bolt ONLY (NNN) NNN-NNNN69 4.001 (2.3" main) 2 bolt (NNN) NNN-NNNN88 4.001 (2.3" main) 2 bolt (NNN) NNN-NNNN4.001 (2.45" main) 2 bolt (NNN) NNN-NNNN69 4.001 (2.45" main) 4 bolt (NNN) NNN-NNNN96 4.001 (2.45" main) 4 bolt (NNN) NNN-NNNN72 4.126 (2.65" main) 4 bolt (NNN) NNN-NNNN80 4.126 (2.65" main) 2 bolt

Notes: 2 bolt ONLY means what it says. You will NOT find a 4 bolt 305 block (made by the factory). Period. Otherwise 2 or 4 bolt can mean either design...

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)

Engine Plant Code
Flint (Motor/6-cyl) F
Hydramatic H
St. Catherines, Ontario K
(McKinnon Industries Canada)
GM of Mexico M
Saginaw Service S
Tonawanda T
Flint (Engine/V8) V


Casting Clock

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

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 XXXXX 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)

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).
