Livernois LS2 404 cid Long-Block

Livernois Motorsports has a 36,000-square-foot facility containing a cylinder head development center and full machine shop, as well as a complete parts store, among other things. The staff also does PCM tuning. Among the company's offerings is this stroked-and-poked LS2. This long-block installed in a 2006 C6 Corvette made 500 horsepower at the rear wheels (560 on a Superflow engine dyno), while being very streetable and retaining stock-type idle and drivability.

Rapid Motorsports 402ci LS2 Dominator Series Long-Block

Rapid Motorsports has been building LS-series engines since their release in 1997, and designs and builds everyday streetcars to all-out-wild racecars. Designed for serious street/strip use, this crate engine has produced 553 rear-wheel horsepower on pump gas. Rapid Motorsports uses only high quality components, holds strict machine tolerances, and starts this engine off with a brand-new GM block.

SDPC "The Jefe" 402ci Crate Engine

For those of you who have yet to be arrested after a fun-filled night in Tijuana, "Jefe" means "boss" in Spanish, and that's a good name for this big-cube engine. It even includes MSD coil packs, Aeromotive fuel rails, and Katech valve covers. Scoggin-Dickey offers crate engines of its own (like this sucker) and is also a full GM Performance Parts dealer. So whatever type of GM engine you're looking for, be it straight out of the GM crate or built to the hilt by SDPC, these guys and gals have it covered. Says SDPC's Kris Jones, "we have a complete race shop with engine dyno ready to build your street thumper or your full race monster!"
