DISCONTINUED - LS 364/440 - A high-tech small-block with a carbureted twist

The General Motors LS Family of small-block engines broke new ground with efficiency and power levels never before imagined. GM Performance Parts offers several of these engines as complete assemblies ready to bolt in to your project car as a replacement or upgrade. And now for the first time, GM Performance Parts has taken one of our LS2 engines and added to it a blast from the past—our LS1 4-barrel intake manifold!

Based on the LS2 engine, the LS 364/440 ships with an aluminum LS block, which has a deep-skirt and six-bolt mains. Other features include lightweight flat-top pistons with a 10.9:1 compression, powdered-metal rods, and a nodular iron crankshaft. The LS6-style cylinder heads are truly high performance pieces that deliver large amounts of air to the awaiting engine. The camshaft specs out with .500/.500" lift numbers, and has been specifically designed to work with the LS Family.

The LS 364/440 is easy to install with all of the major components shipping to you in one big box. Take advantage of this opportunity to enjoy the latest evolution of the small-block Chevy. The LS 364/440 is rated at 440 horsepower and is a true blending of new technology with a proven air/fuel induction piece.
