How To Select The Right GM Crate Engine For Your Lowrider.
November 01, 2007
The LS7 gives you "7 liters of pure troublemaker." The king of all Corvettes is the ZO6. It tops out at 198 mph, runs the quarter mile in 11.5 seconds at 127 mph, and hits 60 mph in 3.5 seconds (in first gear). All of that performance is the result of GM engineering and an engine called the LS7, claimed by GM to be the most technologically advanced small-block ever built. A natural continuation of the LS family, the LS7 uses a 7.0-liter aluminum dry-sump block, CNC-ported cylinder heads, and titanium rods and valves to pump out 505 hp and 470 lb.-ft. of torque. And it's surprisingly efficient. The LS7 helps the ZO6 get more than 28 mpg while still being the fastest Corvette ever produced! This may be the Chevy small-block in its highest form. GM Performance Parts is offering the legendary LS7 as a complete crate engine, ready to bolt into your favorite project car. The LS7 will set you back $12,995.

The LS1 is fast becoming a new small-block legend in its own time. GM released a redesigned small-block in 1997 known as the LS family V-8 small-block. The first and most popular version is the high-performance LS1, which is available as a complete crate engine from GM Performance Parts. A deep-skirt, six-bolt main block, with structural oil pan and other carefully engineered features helps make the LS1 a strong, smooth-running and dependable engine. A high-lift camshaft actuating big 2.00/1.55 valves in symmetrical-port cylinder heads helps make it an uncompromised performer. The engine is rated at 350 horsepower and 365 lb.-ft. of torque, and includes a GTO-style oil pan, electronic drive-by wire throttle body, intake manifold, exhaust manifolds, fuel rail with injectors, balancer, and 14-inch automatic transmission flexplate. It makes a great performance engine for your performance vehicle project; just add wiring and electronics. A handy reference guide is available to help install the engine in older cars with minimal guesswork. Uncrate this crate at $8,598.

GM claims that their 454 is the "stuff that legends are made of," and provide "big-block, street-sweeping power just like the '60s GM muscle cars." Now, GM Performance Parts has a 454-c.i.d. crate engine that's big on power and low on dollar. They started with a brand new (not remanufactured or sourced from a scrapyard) Gen VI four-bolt big-block. The 454 HO is stuffed with a forged steel crank, forged connecting rods and forged pistons. A roller camshaft with .510/.540-inch lift generates a nasty idle. Cast iron cylinder heads deliver a pump-gas friendly 8.75:1 compression ratio. Horsepower comes in at 425 with 500 lb.-ft. of big-block torque. The 454 HO is delivered to you complete with water pump, balancer, intake manifold and 14-inch automatic transmission flexplate. Add your carburetor, ignition and starter to complete the engine. All of this can be yours for $8,309
