I have been reading a book titled Chariots of Iron written about the 735th Tank Battalion of WWII. In it I learned that Chrysler built M3 and M4 tanks with 5 of their automotive inline 6 cy. engines connected to a common drive making for a 30 cylinder tank. Very interesting and I had not heard that before. The book also notes a V8 Ford engine used later that was 1100 ci with 500 hp and 950 lb ft of torque in the M4A3E8 tank. That would pull stumps! S
