Chrysler Hemi FirePower V8 Engine Rebuild Time-Lapse (I put a 354 in a '56 Ford Pickup when I was 15)
I was watching a cable TV show on the Velocity channel about the 70s era in NASCAR. They said that a top pit crew could replace an engine in 20 minutes! I wish car dealers worked this fast, then maybe their hourly rates wouldn't be so high.
