V8 Engine Building Kit
. 8 1/5 H x 11 1/4 W x 8 1/2 D. Lubricated with small applications of vegetable oil, the engine operates using a small battery-powered electric motor (requires three AA batteries) which makes an ignition sound while firing the spark plugs; the valve sequence cycles, the pistons move, the shaft rotates, and the timing belt moves with the radiator fan belt. A transparent cylinder block enables young mechanics to see how the connected parts work in concert to power a vehicle.
