1964-1971 Champion Engine Tune-Up Chart - Passenger Cars & Light Trucks Index

This is the cover/index page of a Champion Spark Plug Company "Engine Tune-up Chart for Passenger Cars and Light Trucks," covering model years 1964–1971. Published by Champion Spark Plug Company of Toledo, Ohio, U.S.A., the booklet is a vintage service reference chart. The cover shows a red-tinted photograph of technicians working on a car engine with diagnostic equipment, along with the Champion bow-tie logo and a spark plug illustration. The visible index lists page locations for U.S. passenger cars by year (1971 on pages 1-4 through 1964 on pages 28-30), imported passenger cars (Datsun, Fiat, Opel, Toyota, and Volkswagen on pages 31-34), and light trucks by year (1971 through 1964 on pages 35-50). Additional reference sections include engine codes (pages 51-53), timing mark locations (pages 54-60), and service condition analysis (page 61). A reader can use this index to locate tune-up specifications—such as spark plug data, timing marks, and engine codes—for American cars and light trucks and select import brands from 1964 through 1971. The document is hole-punched at the top, suggesting it was designed to hang in a service shop.
