In case anyone is interested in the "Monster" photo in the last edition of RandC, the engines used in the 4 engine dragster are Allison W-24 engines. They are the result of mating two model 1710's to a common crankcase to make a w-24 model 3420. The engine came in an optional turbo-supercharged version. They made 2,600 hp @3300 rpm in military trim at 25,000 ft. alt. That's 10,400 hp., no wonder they didn't drive it!!
