I had all the issues as I show you how to swap an LS cam. I show you what to do if your lifter guides are warn out and will not hold the lifters away from the cam shaft. I show you how to do an VVT delete and how to make sure your pushrods are the correct length. This video will be one of my one stop shopping videos, so I have included all the torque specs that I am using on my LY6. Below are the links for everything I used for this swap...tuning videos to come.
