Chevy LS327 - 5.3 Liter

The original 327 was a legend that is still impressing new drivers. That 327 found its way into Camaros, Corvettes and a few other high performance GM cars of the day. That engine was known for its ability to run at higher RPM's which works well at most race tracks. GM Performance delivers a new 327 in the form of a 5.3 liter - 327 horsepower small block LS. That is one horse per cubic inch. GM LS327's freature components to make it a high revver, just like the 60's 327. A hotter cam, Grafal-coated high-silicon pistons and more add up to an LS engine that is fun to drive.
