How Can I Make The LS7 Engine Faster?

Golen Engine is your home for LSx and LT1 engines!

Are you looking to build an absolute BEAST of a car? Do you have a 2006 Corvette that you want to be even FASTER? Take a look at Golen Engine Service, and you will see why they are an industry leader in solid performance engines!

The LS7 displaces 7.0 liters - 427 cubic inches - and is standard equipment in the 2006 Corvette Z06. It is identified by red engine covers and is based on the new Gen IV small-block architecture.

Unlike the previous Corvette Z06 engine, the LS7 Engine has a separate and distinct engine block casting and reciprocating assembly than the base Corvette engine. And when compared to the LS2, it has a different front cover, oil pan, exhaust manifolds and cylinder heads. 

The unique block accommodates large-displacement cylinders, while other components make use of racing-derived lightweight components to help boost horsepower and rpm capability.

The LS7's specifications are significant for a production engine:

• 505 horsepower @ 6200 rpm
• 475 lb.-ft. of torque @ 4800 rpm
• 7000-rpm redline
• Unique engine block with larger 104.8-mm (4.125-inch) bores and pressed-in cylinder liners
• Forged steel crankshaft with 101.6-mm (4-inch) stroke
• Titanium connecting rods
• Cast aluminum flat-top pistons
• Racing-derived CNC-ported aluminum cylinder heads with titanium intake valves and sodium-filled exhaust valves
• Dry-sump oiling system
• 11.0:1 compression ratio
• Camshaft with 15-mm (.591-inch) lift
• Hydro-formed exhaust headers with unique "quad flow" collector flanges.

All LS7 engines are assembled by hand at GM's new Performance Build Center in Wixom, Mich. The exacting standards to which they are built include deck-plate boring and honing of the cylinders and even crank line-boring of the block with the deck plates and side bolts installed - procedures normally associated with the building of racing engines are almost unheard of in a production-vehicle engine.

"In many ways, the LS7 is a racing engine in a street car," said Dave Muscaro, assistant chief engineer of small-block V-8 for passenger cars. "We've taken much of what we've learned over the years from the 7.0-liter C5R racing program and instilled it here. There really has been nothing else like it offered in a GM production vehicle."

Indeed, the LS7's engineers spent as much time at racetracks as they did at engine dynamometers. Everything from the cylinder heads to the unique dry-sump oiling system has a direct line back to the racing program. But while the LS7 has racing roots, it delivers its performance with uncompromising smoothness and tractability - qualities that make the Corvette Z06 a daily-drivable supercar.
