Hagerty’s Redline Rebuild team tears down and rebuilds a Ford Flathead V8 pulled from a 1946 Ford pickup, an engine that had already logged more than 4,000 miles as part of the network’s Swap to Street build before earning a proper rebuild. Six days of work and more than 40,000 photographs get compressed into a fast-moving time-lapse that shows exactly what it takes to bring one of the most important engines in American automotive history back to full strength. Watch to see the flathead get the treatment it’s earned.
