Default GM Performance Parts 427ci / 505hp ''LS7'' Engine

I wonder if GM will be selling the bare block? Here's the vanity plate I am thinking about getting next summer
427BIRD

PRICE $12999.99USD
GM Powertrain, using valuable data gleaned from the factory-sponsored Corvette C5R racing program, developed the LS7 with many competition-derived components and design features. It takes production small-block performance to an unprecedented level while demonstrating the continuing adaptability of the engine’s compact, cam-in-block design. It is, quite simply, the largest, most powerful production small-block V-8 GM has ever produced.

Forged steel crankshaft with 4-inch stroke
Titanium connecting rods

Hydroformed exhaust headers with unique “quad flow” collector flanges
Each engine assembled by hand by a single, specially-trained builder

Engine processor
Air filter/air box
Accessories or accessory drive
