Hagerty has this Redline Rebuild series of videos. Here is one where they take a V8 engine apart, off to machine shop, show all steps in the refurb, back to reassembly, paint, bolt up, and finally on an engine start-up stand. All in about 10.5 minutes of video. Great photography, awesome V8 sounds through the exhaust pipes, unmistakable! Hope you enjoy
