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.
