Many late-model small-blocks rate the engine size in liters (such as 4.3L, 5.0L, or 5.7L), and this number is cast into the ledge at the rear of the block on the driver side. It is possible to fake engine numbers, trim tags, VIN plates, and other documentation, all in an effort to increase the resale value of a vehicle.
Be careful! These days some rare vehicles with rare options have become high-dollar investments. Also, criminals may have re-stamped the block in order to fake a more valuable or rare matching numbers block.

Engines that were replaced under factory warranty might use the CE suffix code or may not have any assembly or suffix code information at all. If the block has previously been decked (a machining operation to ensure the flatness of the block surface or to reduce the piston deck to block deck height to 0), these stamped letters and numbers may have been machined right off the passenger-side block deck surface and may no longer be visible. This 350 block (5.7 liters) features a one-piece rear main seal and was obviously cast in Mexico. Late-model blocks have their casting number on the rear ledge of the case along with the original size of the motor indicated in liters. Knowledge of the correct casting numbers, date codes, suffix codes, and engine assembly code stampings help a buyer decide whether a 1965 Corvette with a 327/375-hp fuelinjected engine is an original numbersmatching car or not. Whether the numbers match can be extremely important to someone who is buying a restored or restorable classic and it can have an effect on the desirability, originality, and value of the vehicle. Even more information is available on the trim tags, VIN plates, and hidden VINs and casting numbers, codes, and dates, which are found on other major powertrain components and vehicle frames. The number also indicates that the car was a Chevy II that was the 23,456th vehicle assembled in the series.Īll of these casting numbers and stamped numbers are consulted when someone wishes to determine if this is a numbers-matching engine and vehicle.

Finally, on later blocks, there are also numbers that match the last five, six, or seven digits of the Vehicle Identification Number (VIN) that has been assigned to the vehicle.Īn example of a hand-stamped engine assembly date and suffix code looks like this: F0213ZE 023456, which translates into an engine assembled at the Flint (F), Michigan, factory on February 13 (the second month, 02, thirteenth day, 13)-years are not stated here-and a 327/250-hp engine (in 1965) with a manual transmission and A/C (ZE). At the end of the stamped symbols, the one-, two-, or three-letter engine suffix-code identifies what type of motor it is, what type of vehicle the motor went into, what type of transmission was originally mated to the engine, and other features. The stampings show the month and day of the month the engine and vehicle assembly took place. These stamped symbols are visible after the motor is assembled. These stamped letters and numbers are usually found on a ledge forward of the number-2 cylinder on the passenger-side deck of the block. The engine assembly date and which factory assembled the engine are indicated by numbers and letters that are stamped into the block when the engine is assembled and placed into a specific vehicle at the factory. Casting dates should precede hand-stamped engine assembly dates. A 1968-model Camaro assembled on January 6, 1968, might contain a number of parts that were cast in December 1967. General Motors 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. This is not the date when the engine was assembled. The block casting date, which is the date the block was made, is found on a ledge at the rear of the block.
