Here’s where it gets good. For 2008, Dodge has increased horsepower to from 510 to 600 and torque from 535 lb.-ft to 560 lb.-ft. This was accomplished with a larger bore that increased displacement from 8.3 to 8.4 liters, new cylinder heads, larger valves, variable valve timing on the exhaust side and better cooling and breathing. Also new is a smaller-diameter twin-disc clutch that reduces pedal effort and improves engagement feel and an optional external transmission cooler.
