I am putting in the Performer spec cam today and I am debating about putting it in with 9* advance up from the 5* it is if you put it in out of the box straight up. I already have a 3 keyway crank gear so its a matter of pulling it off and moving it. Running it through engine analyzer pro I will pick up little torque across the board. Should I mess with it? Any down falls to doing it? I need some input pretty quick I have all of the springs changed and I am about ready to start reassembly.
