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.

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!"
