This starts off as a stock OEM ATS-V camshaft.  We then modify the fuel pump lobe on it.  This increases the lift of the factory mechanical pump by 45%.  Some people have had engine failures from simple bolt on cars without this mod.  It is an absolute MUST HAVE for anyone wanting to flirt with E85 fuel, and still a must have for some people on gas.  This works very well with our ATS-V tune and Flex Fuel Conversion Kit. The LF3/LF4 is extremely hard to keep timing correct, so we highly recommend our Cam Sprocket tool which can be found here.  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 45-60% ethanol with this cam and our tune (however each car is going to be slightly different). 

With this cam we press the larger fuel lobe on just like factory, we then weld the lobe as an extra measure.
