Just your typical WWII Sherman tank Ford V8: 1100 cid, 525 hp and 1000 ft-lbs of torque! (The Mitchell Collection, Montgomery, Texas) Full details on this monster here: http://en.wikipedia.org/wiki/Ford_GAA_engine
High Performance Ford 4.9 inline six. Wow...this little beast has been around since 1906 (first generation). The second generation was used in the F-series pickups starting in 1952, but was most well-known (3rd generation) starting in 1960 with the Falcon. Ford at its best.
