Car-company intelligence is way more reliable than that of our national government, so the Deciders at Dodge have known with absolute certainty that the Bow-Tie Boys have been hard at work on a whopper of a WMD for a couple years. So they're launching a preemptive strike with their own Weapon of Mass Displacement -- a significantly revised V-10 packing a nice round 600 horses and 560 pound-feet of torque, and all of 'em SAE certified. So where'd they find an extra 90 horsepower and 25-pound-feet? In the three places all racers know to look:
More Displacement
- An extra millimeter of bore (to 103 mm) boosts capacity from 8.3 to 8.4 liters
- Pistons and rods borrowed from the 6.1-liter SRT-8 Hemi V-8s boost compression ratio from 9.6:1 to 10.2:1
- Iron liners are pressed into a block with improved water jackets for more efficient cooling
Higher Revving
- Hollow-stem intake valves lower weight
- Investment-cast intake rockers further reduce valvetrain inertia
- Pistons get larger-diameter wrist pins and bronze bushings
- Powdered-metal connecting rods use aircraft-quality fasteners for increased fatigue strength
- Cross-bolted main-bearing caps improve strength and durability
- A larger oil pump with a swinging pickup (adapted from the Viper Competition Coupe) improves oil pressure under high-rpm and high-g operating conditions.
