Makerhaus specializes in various auto and electronic products, including this 1:3 scale model of the high-performance 289-cubic-inch V-8 that Ford installed in early Mustangs. This one moves with the help of three AA batteries (not included). The cooling fan spins, the crankshaft turns, the pistons move up and down and the spark plugs fire (or appear to fire) using red-tipped LEDs. An electric sound module produces a simulated engine growl. A collector’s manual covering the history of the Mustang V-8 is also included with the 200-piece kit.
