There is documented proof that these engine plants would increase production leading up to possible strike periods, making it highly probable that many cars were built with engines way ahead 6 to 9 months of thir respective build date.
Another thing to consider if you have an original, untouched car, is to match the casting dates of the original parts still remaining on your car.
This procedure can prove to be dangerous unless you can verify that these dates still coincide with the build date. Block Casting Number Identification.
The block casting number is the single most important number on a block because it will probably be the last number on a block to be altered or changed to counterfeit or misrepresent a block. The casting number is usually found at the rear left side of the block, on top of the bellhousing flange. The casting date codes are cast in an alphanumeric sequence.
The first digit will usually be a letter code, which specifies the month the block was cast. These types of dates are not common in restoration circles. The month code letter designations are as follows:.
A — January G — July. B — February H — August. C — March I — September. D — April J — October. The remaining digits in the date refer to the day of the month and year of the block casting. Cylinder Head Casting Numbers. The cylinder head casting number is the single most important identifying feature on a head because, just like the block casting number, it will probably be the last characteristic to be altered or changed.
The casting number is usually found in between two valves and the rocker arm studs underneath the valve cover. The casting date is usually found adjacent to the casting number. The casting date codes on small block cylinder heads can usually be found directly underneath the casting number. The first digit in the casting date code will usually be a letter code, which specifies the month the head was cast.
The remaining digits in the date refer to the day of the month and calendar year of the head casting. NOTE: It should be noted here that some engines will use the same casting number, but have a different valve size. Due to space limitations, the differentiating features of each cylinder head could not be included in this article.
This information will be included in a forthcoming article. Also, the external identification symbols that are cast into the ends of each small block cylinder head could not be included in this article due to space limitations.

Most casting numbers are visible when the manifold is installed on the engine. The casting number location and casting date location will vary from year to year and sometimes manifold to manifold.
Some manifolds will not carry a casting date at all. Casting date codes follow the same pattern as engine blocks, but some do not carry a year.
