LF3/LF4 Camshaft with Upgraded Fuel Pump Lobe

The ZZPerformance LF3/LF4 Camshaft is a modified OEM ATS-V camshaft featuring a new, larger billet fuel pump lobe. This modification increases the lift of the factory mechanical fuel pump by 40%, providing the necessary fuel volume for performance applications, particularly when running E85 fuel blends. This camshaft is considered a crucial component for achieving higher ethanol content in your fuel system. To maximize the benefits and ensure proper operation, ZZPerformance recommends pairing this camshaft with their ATS-V tune and Flex Fuel Conversion Kit. For optimal fuel delivery with higher ethanol concentrations (approximately 45-80%), it should also be used in conjunction with an upgraded in-tank fuel pump. ZZPerformance also suggests using their ZZP Cam Sprocket tool for easier and more accurate installation, as setting the cam timing on the LF3/LF4 can be challenging. This camshaft is part of ZZPerformance's "10 second ATS-V car recipe" and is recommended alongside other performance upgrades such as their ATSV Tune, Downpipes, Cold Air Intake, Flex Fuel Conversion Kit, and 82# Valve Springs.
