Watch Davin explain the Stovebolt Six Redline Rebuild - Hagerty Media

The latest Redline Rebuild has been one of our most popular builds yet. The Stovebolt inline-six yanked from a derelict 1950 Chevrolet 3600 roared to life before Davin pulled it, but it still deserved a rebuild. The whole process was captured in a time lapse seen by millions, but behind the scenes there was a lot going on. Davin and Ben sat down to talk through the process and interesting points, and their debrief is worth the watch.

Of course the time lapse is beautiful and fun to watch, but why did the connecting rods come out with babbitt bearings and go back in with insert bearings? Ben clicks through, frame by frame, while Davin explains a few of these finer points—like those babbitt bearings, which he chose to swap for insert bearings due to ease of assembly and machining.

Another step in the process that Davin addresses—one that’s often marked in the Redline video comments—is his use of Glyptal, the heavy red coating brushed onto select parts of the engine block during assembly.

“I use it to seal up the metal, preventing any rust from forming during long periods of storage where the engine oil completely drains back to the pan,” said Davin. “It also helps the oil flow back to the pan a bit quicker, which can help these older engines shed heat better.”

Did you catch the odd oil-line routing in the time lapse? Probably not, but it was one of the things that stuck out to Davin during disassembly. He talks about that hard line and so much more, making this rundown well worth a watch if you are curious about the process or some of the intricate bits of the Stovebolt series engines.
