PLUM CRAZY

Getting back to the diesel, the difference in output is startling compared with the engine used in the original ’29 Plymouth. Chrysler introduced an inline four-cylinder version of its straight six in 1926 (just as Cummins had a four-cylinder version of its 5.9L straight six). But that’s where any similarity ends, aside from the type of fuels used. The Chrysler displaced less than 2.8 liters and churned out 45 horses. The 1,200hp Cummins delivers 26 times that output, plus 2,100 lb-ft of torque. Is that crazy or what?
