The stock cubic centimeter (cc) displacement of a Chevy 350 small-block head isn't a single number. The combustion chamber volume varies depending on the year of manufacture and the specific casting number of the cylinder head. You'll find a range, typically between
64cc and 76cc.
To know the *precise* cc for a particular head, you need to identify the casting number stamped on the head itself and then look up the specs for that casting number.
