PERFORMANCE NEWS 4 ntroduced to the public at Detroits North American International Auto Show in January of 2005, the 2006 Chevrolet Corvette ZO6 is quite simply the most amazing performance vehicle ever produced by General Motors. This stunning automobile will run 198 mph, cover the quarter mile in 11.5 seconds at 127 mph, and rip from zero to 60 mph in only 3.5 seconds. The heart of all of this performance is the incredible LS7 small-block V8 offered to the general public for the first time in crate engine form as part number 17802397. Calling the LS7 a small-block just doesnt seem right as it displaces a familiar 427 cubic inches and cranks out 505 horsepower at 6300 rpm with an accompanying 470 lb.-ft. of torque. Based on the modern LS Family of small block V-8s, the LS7 has taken pushrod technology to the next level. CNC-ported, high-performance cylinder heads with a 70 cc combustion chamber lead the intake charge along with a high-lift (.591") hydraulic roller camshaft that revs to redline faster than imaginable. The valve train consists of 1.8:1 rocker arms (offset on the intake side), titanium 2.20" intake valves, and 1.61", sodium-filled exhaust valves. The bottom end is a fortified masterpiece featuring a 6-bolt main aluminum block, forged steel crankshaft, aluminum pistons, titanium connecting rods, and a custom internal dry sump oiling system pure race car stuff unleashed on the streets of America. These hand-assembled engines are individually hot-tested and validated before they ever leave the factory. They also feature a pumpgas-friendly final compression ratio of 11:1,which makes them both amazingly powerful while streetable at the same time. Designed from the ground up to dominate the competition, the LS7 small block is the ultimate in efficiency on the street or strip. When you buy an LS7 crate engine, you are getting the largest production cubic-inch small block that GM has ever produced along with the most advanced engine technology ever offered to the general public. The LS7 crate engine is available immediately from GM Performance Parts authorized dealers and sells for around $16,995. othing matches Utahs Bonneville Salt Flats for testing the absolute limits of man and machine.

It is loaded up with an 800+ horsepower, four-cylinder Ecotec that pushed the 3200 HHR to an amazing 208 mph pass. This HHR not only looks hot, but it will back up those good looks. And, the Chevrolet California Street Rods Student Project Cobalt SS is just as impressive, and assembled by four female engineering students. It went 140 mph in testing and is powered by 230 horsepower version of a turbocharged 16-valve Ecotec four cylinder.
