==Suffix code==
The suffix code is located on a machined boss located on the front passenger side of the block where the head and block meet.

There may be a partial VIN number in one string of letters and numbers and the suffix code will be at the end of a second string of letters and numbers.

If the block has been resurfaced (decked), the codes might have been removed and in that case the date and casting numbers will need to be used to ID the parts, along with any other visual cues that may be available.

==Date code==
The date code is located in the same area as the casting number on the Chevy V8 engines.

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. 
:Example: '''C124''' 
:*C = March (A = Jan., B = Feb., etc.)
:*12 = day of the month
:*4 = year ending in 4, i.e. 1964, 1974, 1984, etc.
