This is what a 2010 viper has

With a 1mm bore increase over the previous generation engine, the new 8.4-liter (510 cubic inch) A356 T6 aluminum block 90 degree V10 motor now achieves 600 horsepower at 6,000 rpm and 560 lb-ft of torque at 5,100 rpm. An assembled steel articulating CamInCam® camshaft, that allows variable exhaust valve timing, along with the new VENOM engine controller, with massive processing power, provides the necessary technology to achieve these very high output levels and still meet idle and OBD requirements. Other new features for the V10 include: - New cylinder heads with larger valves, CNC chambers and throats - Flat top piston with 10.2:1 compression ratio - Race tested swinging oil pickup from the Dodge Viper Competition Coupe - Dual electronic throttle bodies (ETC) - Low restriction induction system with dual mass airflow control (MAF) - Air-gap headers and low restriction exhaust system - Individual high energy coils for each cylinder - Platinum tip spa
