“This is a detailed model of the original 1966 Porsche 911 flat-six engine, all internal parts move just like they do in the full-size engine – including the pistons, connecting rods, crankshaft, cam, valves, and rockers – the spark plugs are LEDs and you can see them illuminate to simulate spark timing.“

Pelican has been selling these for quite awhile. They used to have specials on them at the toys and literature show. I wish it came with a shroud so it looked more authentic, still way cool!!
