If you're a billet aluminum fetishist, then today is your lucky day. Kirkham Motorsports loves aluminum and it uses the metal to build the bodies of its Cobra replicas and engine blocks. The engine blocks are billet pieces machined from a single block of aluminum – a 386-pound chuck of aluminum.
That piece of heavy metal is placed into a CNC machine where it's eventually whittled down to a 64-pound billet aluminum 427 engine block. The process requires 30 hours of CAD work, 50 hours of programming and finally 30 hours of machining. Put on your safety glasses and click past the jump to watch a replica Cobra heart born.
