1964 Casting Numbers

The information below pertains to available production in 1964. If the application covered the 1964 model year it is listed here. All information here is for V8 engines only, I have the L6 information but seeing how the V8 is more popular I have decided to omit that portion due to the amount of time that it takes to put it all together. Where there is L6 information it will be denoted by and asterisk (*). Also the items listed here are for Chevelles, but many parts were used on other models as well and they are noted. Many parts were used in 1963 as well as later years, determining date codes is discussed on another page. Also provided are part numbers on some items
