Welcome to the Early Mustang Technical ArchiveThe goal is to create a repository of useful information that is scattered throughout the internet, sitting someone's garage or shop, or parked in the brain of some of our fellow owners who are just good at this stuff.Please consider contributing (information, not money!)Below you will find sections on all things Early Mustang including:

• Technical Articles on valuable topics such as engine oils, mechanical vs electrical fans & parasitic draw, engine coolant studies and electrical tips such as use of relays and wiring schemes.
• How-To Articles covering a broad range of user-submitted write-ups such as brake modifications, alternator swaps, shifter modifications, voltage drop testing and a myriad of helpful information.
• Factory Codes & Info section covers in depth configurations of early mustangs with casting numbers, prefixes and where on the car to find them including engine blocks, transmissions, differentials and other build areas.
