The LS7 engine in the 2007 Chevrolet Corvette Z06 gets to 60mph in the time it takes to inhale, and keeps on going. Its heads-up display makes it easy to check the speed as you blast forward, while the tires keep a tight grip on the road. The LS7 engine is accented with custom body-colored engine covers and a beefy BMR strut tower brace was added to the bay. The air intake tube is a custom aluminum unit. The LS7 engine puts out 505 horsepower in stock form, so it could really use about twice that. APS claims their power adders will get the LS7 engine generating upwards of 1100 rear wheel horsepower.

Intake airflow is up some 43 percent over the LS6 head, while the exhaust shows a 26 percent gain. In terms of flow capacity, that's serious territory, far beyond any factory Chevy small block head of the past, and well past any production big-block heads. Intake valves and connecting rods are titanium. If you haven't actually felt titanium, it's eerily lightweight, like some kind of superdense plastic, only cold to the touch.

Oil circulates through the engine and down to the oil pan, where it is sent back to the reservoir via a scavenge pump. The large-capacity reservoir, combined with a high efficiency air-to-oil cooler, provides necessary engine oil cooling under the demands of the engine’s power output. Oiling system: The LS9 uses a dry-sump oiling system that is similar in design to the LS7's system, but features a higher-capacity pump to ensure adequate oil pressure at the higher cornering loads the ZR1 is capable of achieving. An oil-pan mounted oil cooler is integrated, too, along with piston-cooling oil squirter's located in the cylinder block.

GM canceled the option even though the LS7 engine option is listed in some early 1970 sales literature. None were ever sold. GM's plan for the LS9 included a supercharger, and it felt the 427 cubic-inch block wasn't strong enough to reliably hold up to the intended boost. Instead, a beefed-up 6.2-liter LS3 block will be used.

Intake flow efficiency was optimized by straightening out and optimizing the flow path from the intake manifold into the cylinder heads. A high flow efficiency induction system is borrowed from the Z06 application. Intake manifold, tb, oil pan everything including exhaust manifolds.

Power steering system on it. Sweet MFG makes a pump and pump bracket for the 350 Chev for the left (drivers side) cylinder head. Powered by the new LS7 7.0 liter engine, it delivers an earth shattering 370kW and 640Nm of torque. Featuring an exclusive active exhaust flow management system, bold supercar styling, 20-inch alloy wheels and magnetic ride control, it's set to take on the world.

The LS7 engine is not substantially heavier than the 6.2 liter it replaces. That car also includes carbon fiber body panels. The LS7 engine will be fitted at HSV?s Clayton plant along with the same dry sump system used by the Z06 Corvette. HSV are considering offering new owners the opportunity to visit HSV to see the W427?s manufacturing process for themselves. The LS7 engine has kept only the aluminum block. Everything else has been upgraded to stand the pressure two superchargers impose to reach the high output and the torque of 1,050 Nm at 3,900 rpm.
