Hello all, I could use some help to figure out what this engine is and where it came from. Thank you in advance for any info you can share. Block casting 3914678 with V1117B4 and 781120204 on the id pad. Head casting 3795896
No that's the correct sequence. first number is Division. 1 would be chevy. 7 is Canadian Pontiac division. What they do for the engine vin is remove the 4 number series and body style from the vin number. That leaves you with Division, year,plant and sequence number.
Here is a sample from Nasty Z28 Also check out with Chevy by the numbers book.
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)
