Product Details

If you're building a high-RPM street or strip engine for your LS3 or LS7, fine-tuning the powerband is key. These short velocity stacks from FAST are designed to help you do just that, specifically shifting torque and horsepower to the higher end of the RPM range. They fit directly into the FAST LSXHR 103mm intake manifold, allowing you to swap them out and experiment with different combinations.

This set includes the short stacks, which are one of three available lengths (short, medium, and tall) that FAST offers for the LSXHR manifold. By mixing and matching these stacks, you can effectively tune your engine's power delivery on a cylinder-by-cylinder basis, aiming for the best possible performance in your specific application. This level of adjustability is great for getting the most out of your build, especially when you're pushing the engine hard at higher RPMs.

This product fits a wide range of GM vehicles, including popular models like the Chevrolet Camaro, Corvette, and Silverado, as well as Cadillac Escalade and GMC Sierra. It's a straightforward way to make a notable change to your engine's breathing characteristics and overall performance profile.
