The Ford GAA engine is an American all-aluminum 32-valve DOHC 60-degree liquid-cooled V8 internal combustion engine with a flat-plane crank designed and produced by the Ford Motor Company before and during World War II. It features twin Stromberg NA-Y5-G carburetors,[2] dual magnetos and twin spark plugs making up a full dual ignition system,[2] and crossflow induction.[3] It displaces 1,100 cu in (18 L) and puts out well over 1,000 pound-feet (1,400 N⋅m) of torque from idle to 2,200 rpm. The factory-rated net output was 500 hp (370 kW) at 2,600 rpm.
The GAA powered several models and derivatives of the M4A3 Sherman medium tank.
