DOHC V8 out of Legos
You are looking at a "working" Lego V8 engine. And the details are stunning. Pistons pump, valves open and close, rocker arms rock, the fly wheel spins — there's even two bundle'o'snakes headers that flow into twin collectors, though we don't like how they get reduced and choked. But hey, if you really don't like it, you can build your own – with straight pipes!
