"The 2008 version of Dodge&amp;#039;s Viper ups the sports car ante with a new, 8.4-liter aluminum V-10 engine that produces an inimidating 600 horsepower and 560 lb.-ft. of torque, according to a company news release.   &amp;quot;With 600 horsepower \u2014 90 more than before \u2014 and 0-to-60 performance in less than four seconds, sets a new benchmark for the ultimate American sports car,&amp;quot; said Kipp Owen, Director \u2014 Street and Racing Technology (SRT) Engineering, Chrysler Group.   Working with specialists from McLaren Performance Technologies and Ricardo, Inc., SRT engineers began by following the racer&amp;#039;s basic formula for more power: bigger displacement, more efficient breathing and higher engine speed, the company said.   The new Viper SRT10&amp;#039;s deep-skirted V-10 aluminum engine block was revised for a 1-millimeter larger bore, raising the displacement to 8.4 liters from 8.3 liters. With strengthened bulkheads and improved water jackets for better cooling, the block includes pressed-in iron cylinder liners and cross-bolted main bearing caps for strength and durability.   The Viper SRT10&amp;#039;s 8.4-liter engine breathes through new cylinder heads equipped with Computer Numerically Controlled (CNC)-shaped combustion chambers, larger valves and Variable Valve Timing (VVT). VVT electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to &amp;quot;breathe&amp;quot; cleaner and more efficiently.   The new 2008 Dodge Viper SRT10 will arrive in Dodge showrooms in North America this summer with a new level of customization options, including five new exterior colors, four new interior color combinations and a new wheel design, the company said.
