The debate between LS and HEMI engines has been a hot topic among performance enthusiasts for years. Both engine families have their strengths, but when it comes to achieving over 600 horsepower, the choice of head and cam package can make a significant difference. This article will compare the best options available for both LS and HEMI engines, focusing on Lingenfelter’s LS offerings and the Mopar HEMI packages.
Understanding LS and HEMI Engines
The LS engine family, developed by General Motors, is known for its lightweight design and efficient performance. On the other hand, the HEMI engine, produced by Chrysler, boasts a unique combustion chamber design that allows for higher compression ratios and power output. Both engines have dedicated followings, making the comparison even more intriguing.
LS Engine Overview
LS engines are popular in the aftermarket community due to their versatility and availability. They are lightweight, compact, and can produce significant power with the right modifications. The Lingenfelter Performance Engineering company has established itself as a leader in LS performance upgrades.
HEMI Engine Overview
The HEMI engine has a storied history in motorsports and street performance. Its hemispherical combustion chamber design allows for efficient airflow and combustion, which translates to impressive power gains. Mopar offers various performance upgrades for HEMI engines, making them a formidable contender in the horsepower race.
Head and Cam Packages for 600+ HP
