The map, which was found rotting in a chimney, was painstakingly restored over several months. When an old, decayed map was brought to the National Library of Scotland, the library thought it was in luck.
Compared to these, most car engines are bland and boring. By most accounts, the Dodge Viper's engine is completely over the top. After all, it's an 8.4-liter naturally aspirated V10 that's good for 645

This DIY ammo box provides rugged and stylish storage for your tools and gear. Vietnam War-era wood ammo boxes make great storage units, but they're tough to find for a decent price and in good condition.
The part of the engine that contains the combustion needs to be kept in tip-top shape. Gas turbine engines on airliners need to handle some serious power outputs. The General Electric CF6 high-bypass engine,
I struggle to descend the stairs leading to the sandy beach at Half Moon Bay, California, awkwardly hefting the 60-pound solar-powered boat SeaCharger atop my shoulder. Amid the numerous “what-the-heck-is-that?!”
