In Ford Flathead Engines: How to Rebuild & Modify, veteran author Tony Thacker and flathead guru of H&H Flatheads, Mike Herman, take you step-by-step through rebuilding a vintage flathead. One of the most important steps is to find a good, usable core; many have been sitting for a very long time and the engine design is prone to cracking. Running changes are also an important consideration when selecting a core, and include cooling system, ignition, and transmission mount. After you have selected a core, Thacker and Herman take you through the entire process of a rebuild, including teardown, parts inspection, machine shop processes, replacement part selection, re-assembly, start up, and break-in.

Also covered is a unique performance build completed at the H&H shop for legendary race car team manager and all-around enthusiast Ray Evernham. It all adds up to more than 500 color photos and insider tips on building what could be called the most iconic engine ever built, the Ford flathead V-8.
