CRATE ENGINES LS SERIES 64 350/290 HP TECH SPECS: A new small-block legend in its own time! When GM dared to release a redesigned small-block in 1997, it succeeded beyond the expectations of enthusiasts around the world. Known as the LS Family V-8 small-block, the first and most popular version is the high-performance LS1 available here as a complete crate engine from GM Performance Parts. In many ways, the LS1 is superior to any small-block that came before it. 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 highlift camshaft actuating big 2.00/1.55 valves in symmetrical-port cylinder heads helps make it a uncompromised performer. The engine is rated at 350 horsepower and 365 lb.-ft. of torque. The engine includes a GTO-style oil pan, electronic drive-bywire throttle body, intake manifold, exhaust manifolds, fuel rail with injectors, balancer, and 14" automatic transmission flexplate. It makes a great performance engine for your performance vehicle project just add your wiring and electronics. A handy reference guide (see page 66) is available to help install the engine in older cars with minimal guesswork.
