COMP Cams Camshaft GM Gen Iv LS 994 Vvt

This is the COMP Cams XFI RPM HI-LIFT camshaft, part number 156-402-13, designed for GM Gen IV LS engines. If you're looking to get more power out of your LS, this camshaft is built to significantly increase performance in the upper RPM range. It's engineered to deliver strong pull from around 4500 RPM all the way past 6700 RPM, making it a great choice for builds focused on high-RPM output. You can expect a noticeable idle with this camshaft, which is a common characteristic of performance grinds that move more air.

This camshaft is a hydraulic roller type, featuring a 218-degree intake duration and a 232-degree exhaust duration with a .570" intake lift and .565" exhaust lift. The XFI RPM HI-LIFT series is known for its ability to handle aggressive valve springs and pushrods, allowing for higher lift profiles. It's constructed with durable materials to withstand the demands of performance driving. This camshaft fits a range of GM vehicles, including models like the Chevrolet Silverado 1500, GMC Yukon XL 1500, and Cadillac Escalade EXT from the 2007-2008 model years.

When installing a camshaft like this, it's important to ensure you have the correct supporting components. This includes a compatible valvetrain, such as upgraded valve springs, pushrods, and potentially a timing set, to match the camshaft's specifications and achieve optimal performance and reliability. Always refer to the manufacturer's installation instructions for detailed guidance.
