The 1468 was an international harvester tractor similar to the 1568, borrowing the same V8 DV-550 engine from the international truck divison. The tractor differed by using the transmisson and accesories from the smaller 1466 model rather than the 1566 model that the 1568 used. The last letter in the model number denotes the number of cylinders, These V8 machines appealed to the younger farmers of the time who liked the hotrod like twin exhausts and the unmistakeable roar of the V8 engine. The DV-550 engine used was unique for the time, as while idleing or ad low load, the engine ran on just 4 cylinders, once more power was required, fuel was sent to the other 4 cylinders thus reaching full power but remaining relatively fuel efficient. to this day the 550 cubic inch V8 remains the largest engine factory fitted into a farmall tractor.
