From this chart - I think you may be misreading the number - 3970010 is possibly the actual number: Which makes the engine pretty old 68-72 350 V8 - 4 bolt main. I included past this number so that you can see that the number you posted doesn't actually exist. And thus my conclusion that the 9 is most likely a 0. Hope this helps. 3970010 350 69 Corvette late 69,4 bolt main 3970010 302 69 Camaro Z/28,Late 69, 4 bolt main 3970010 350 69-79 Truck 2&4 bolt main 3970010 350 69-79 Pass,Chevelle,Camaro,Nova,MonteCarlo 2&4 bolt main 3970010 350 70 Corvette 300,350,370 HP 4 bolt main 3970010 350 71 Corvette 270,330 HP 4 bolt main 3970010 350 72 Corvette 200,255 HP 4 bolt main 3970014 350 69-77 Pass,Chevelle,Camaro, Nova,MonteCarlo 2 or 4 bolt main 3970014 350 69-79 Truck 2 or 4 bolt main 3970014 350 72 Corvette late &undefined;72,200 HP,255HP 4 bolt main 3970020 307 68-73 Pass,Chevelle,Camro, Nova 3970020 307 69-73 Truck 3970024 307 69-73 Pass,Chevelle,Camro, Nova,Truck 3992386 327 68-69 Pass,Chevelle,Camro, Nova,Truck Large Jounal

Find the engine identification tag. Attached at the factory, this tag is normally found on the engine block around the coil bolts. The top line of the tag identifies engine size and model year.

Search the block for the engine block casting number. The numbers are raised, not stamped into the block and consist of seven numeric digits. The digits can be located on either side of the block. The seven-digit number may be followed with a dash and further numbers. These are change codes and are not normally necessary to identify the engine.

EX.:

Locate the casting date is located on the block. It is in standard date coding, 2.25.93, for example and may be located on either side of the block, but is commonly located on the driver's side of the block, above the freeze plugs. The example 2.25.93 decodes as February 25, 1993. The casting date may be near the casting clock, which designates the hour the block was cast. Magnum engines were manufactured from 1993 to 2002, so verifying the date code helps identify the engine.

THE ENGINE SERIAL NUMBER IS STAMPED ON THE SIDEWALL OF THE CYLINDER BLOCK AT THE TRANSAXLE SIDE. THE BODY NUMBERS IS ON THE VECHICLE IDENTIFICATION NUMBER PLATES LOCATED AT THE TOP LEFT OF THE INSTRUMENT PANEL.AND AT THE FIREWALL IN THE ENGINE COMPARTMENT.YOUR VECHICLE REGISTRATION IDENTIFICATION CARD IN GLOVECOMPARTMENT HAS VECHICLE IDENTIFICATION NUMBER.THE 17TH DIGIT CODE IDENTIFIES MODEL - YEAR - BODY TYPE.

Hello there:

Casting dates are usually expressed this way, “C 18 4.” In this example, the “C” means the month of
March, “18” is the day of the month, and “4” is the last digit of the year. This last digit may mean ’64, ’
74, ’84 or ’94, so you must also check the other characteristics of the block to determine in which
decade and year it was made. Some parts have the decade and year cast on them; these identifiers
look like this: “C 18 84.” GM introduced new model years in September or October of each year, so
when you see a casting date of “L 16 7” for example, this indicates a casting date used in the 1968
model year because it translates into December 16, 1967. A 1968 model Camaro assembled on
January 6, 1968, might contain a number of parts that were cast in December, 1967. Casting dates
should precede hand-stamped engine assembly dates.
