This starts off as a stock OEM ATS-V camshaft. We machine the factory fuel pump lobe off and press on our new billet larger lobe on. This increases the lift of the factory mechanical pump by 40%. There are cars that require this additional fuel even on their local pump gas. It is an absolute MUST HAVE for anyone wanting to flirt with E85 fuel. This works very well with our ATS-V tune and Flex Fuel Conversion Kit. The LF3/LF4 is extremely hard to set the cam timing correctly, so use extra care when re-assembling. Paired with our upgraded in tank fuel pump will allow you to run vastly more ethanol over stock. Our complete 10 second package will allow you to run approximately 45-80% ethanol with this cam and our tune (however each car is going to be slightly different).
For ease of installation we highly recommend our ZZP Cam Sprocket tool, found here.
