Identifying Chevy engines isn't that difficult if all that's needed is to know whether it's a BBC or SBC, or a six or V8, etc. But to get into the finer points requires digging deeper. | Identifying Chevy engines isn't that difficult if all that's needed is to know whether it's a BBC or SBC, or a six or V8, etc. But to get into the finer points requires digging deeper. | ||

| + | One of the easiest way to identify a Chevrolet engine is by the casting number (c/n) that is cast into the castings (not stamped). [[Chevy engine casting numbers]] has several sites that are useful. The Chevy V8 block casting number is generally atop the transmission mounting area of the block. The date code will usually be found in the same area, sometimes on the opposite side from the casting number, but not always. | ||
It is common to use just the last three numbers of the c/n when dealing with casting numbers, i.e. block c/n 10243880 would be called an "880" block. Usually the last three numbers aren't repeated but there are cases like the SBC head c/n 462 that- for some unknown reason- was reused 5 times! Fortunately this is rare. | It is common to use just the last three numbers of the c/n when dealing with casting numbers, i.e. block c/n 10243880 would be called an "880" block.

The date code generally has a letter followed by two or three numbers. The letter is the month. The next number or two numbers will be the day of the month. The last number is the last digit of the year. | The date code generally has a letter followed by two or three numbers. The letter is the month.
