It's a video of a CNC machine taking a billet of aluminum and carving out a 427 FE engine block.
Pretty neat stuff.Kirkham Motorsports usually needs about 30 hours of computer-controlled machining to turn a 383-lb. aluminum billet into a 64-lb. engine block for its self-designed 427. Luckily for manufacturing geeks, they've shortened the process to seven minutes for this video.
While it looks like a button-pressing gig once in the machine, the programming for the CNC took 50 hours, on top of an additional 30 hours designing the block itself.
BTW, for those that don't know, a 427 FE is also know as the Ford FE Engine. It powered Mustangs in a 390ci size, especially the Bullitt Mustang from the movie. It's also powered the Ford GT-40, the Shelby Cobras, the first funny cars, several record breaking racing boats and the original Batmobile. On top of that, the manufacturing process for the FE was ground breaking at the time because it used a thin cast process.
The process was used to make most of the engines that many of us can rattle off the tongue now. Ford 302/351, Chevy 350, Dodge 318 and so on all benefited from that process by making the waste minimal and the casting method consistent. That dropped costs and made production fast and easy. The FE isn't just a famous hot Ford engine, it's a pioneer in manufacturing techniques. It was so successful that it had 11 variants and powered all but the smallest Ford's as well as multiple race cars and even industrial applications.The FE block was cast using a thinwall casting technique. Instead of relying on large quantities of metal being poured into molds in unnecessary thicknesses, Ford engineers determined the proper amount of metal actually needed and reengineered the casting process to allow for consistent dimensional results pour after pour. This resulted in less metal being used, lower cost of materials for Ford and lighter engines. A Ford FE from the factory weighed 650 lb (295 kg) with all iron components. With an aluminum intake and aluminum water pump this weight could be reduced to under 600 lb (272 kg). At the time, engines of similar displacements such as the 7 liter offerings from GM and Chrysler weighed over 700 lb (318 kg). This weight savings was significant to boaters and to racers.
