There are many upgrades and refinements in this latest C6 Corvette, making it a true super car with a quicker 0-60mph time of just 4.1sec., and a top speed of 190mph.

These facts are due to the new LS3 6.2 liter, V8 engine that now pumps out 430hp at 5,900rpn and 424lb.ft. of torque at 4,600rpm.. With the new, optional dual-mode exhaust system, borrowed from the Z06, horsepower is increased to 436, and torque to 428ft.lbs. with no increase in rpm. This new C6 is near to perfect as you can get. You can drive it everyday to take care of your personal business, and ready to be easily modified for weekend club racing.

This new iteration of the famous small-block family features a revised, larger-bore cylinder block; high-flow, LS7 style cylinder heads; larger-diameter pistons; revised camshaft and camshaft timing; revised valvetrain with offset intake rocker arms; high-flow intake manifold; high-flow fuel injectors from the LS7; and a new engine beauty cover.The LS3 features an aluminum cylinder block with cast iron cylinder liners. In addition to its larger bores, which help create the 376cu.in. displacement, the block casting also features revisions and machining in the bulkheads that enhance its strength and improved bay to bay breathing. Better breathing for the new 6.2 liter engine is accomplished via new, high-flow cylinder heads. There�re based on the large port/large valve design found on the LS7 engine with larger-capacity, straighter intake ports.

The design optimizes intake flow to the combustion chamber and the exhaust ports are also designed for better flow. Complementing the larger-port design of the heads are larger sized intake and exhaust valves. To accommodate the engine�s larger valves and enable more direct intake port flow, the intake-side rocker arms are offset 6mm between the valve tip and the push rod. Actuating the valves is a new camshaft, with intake-side lobes providing more than a 5% increase in lift. Exhaust-valve lift remains unchanged from the LS2. The camshaft timing was revised to optimize performance with the higher-lift intake cam profile.



Ensuring that the cylinder heads receive all the air they can handle falls to a new, acoustically tuned intake manifold. The composite design is manufactured with a �lost core� process that improves runner to runner variation and reduces airflow losses. An acoustical foam material is used to reduce radiated engine noise; it is sandwiched between the outer top of the manifold and an additional �skull cap� acoustic shell.

Also new beauty covers atop the engine shield the rocker covers and also feature a noise-reducing, acoustically tuned insert to provide a more refined engine sound.

The 2008 Chevy C6 Corvette remains one of the best super-high-performing sports cars on the market. You have to test drive one to believe the bargain and enjoy the ease and fun to drive characteristics.
