I will buy the 1st round
Ok folks, I tried the search but didnt find out much (guess I looked for it wrong).. Today a new S&S 600 cam showed up (Drunk on E-bay) really dont remember buying it but I did my account is down. So my question is what will I need to install iti on my 08 EFI K9.. do I need new springs will it effect my EFI??? But most of all what gain would it give me. is it worth it. I have BR pipes and a k&N. but shes all stock other than that. Thanks for your help. MIke
