About LS1 Engine
The Corvette C5 handles wet and dry land with ease, making use of its Z51 performance package and managing a 0 to 60 mph time of 4.7 quick seconds. A small block LS1 engine is at the center of this chassis. The block features an all aluminum build and distributor-less ignition. These LS1 engines are not only used in Corvettes, but on a number of other GM vehicles, such as the Chevrolet Camaro and Pontiac Firebird. The engine manages up to 350-horsepower on production C5 Corvette models. A LS1 engine swap is common in the automotive community, due to its base power point and potential for turbo charging and supercharging applications. You can order an LS1 crate engine from the vast inventories available on eBay. The LS1 engine responds well to bolt-on upgrades such as cold air intake systems, larger manifolds, and exhaust headers. The better airflow allows denser air into the engine, which creates a bigger combustion. Bolt-on performance horsepower gains range between 10 to 15 percent on LS1 engines.
