Ford decided that additional low-end torque was necessary to work with the slushbox. The stall speed of the torque converter would have been too high with the 3.0, so Ford had Yamaha bore the engine to 3.2 liters (the bore went from 3.5" to 3.62"), bringing the torque peak down in the RPM range while increasing its magnitude. The 3.2 liter engine's torque peak is 215 lb-ft @ 4000 RPM, and the power peak is 220 hp @ 6000 RPM. The corresponding figures for the 3.0 liter engine are 200 lb-ft @ 4800 RPM and 220 hp @ 6200 RPM.
