the cam will have those same specs no matter where the intake centerline ends up. what can change is where valves open and close. If you just line up the dots, the intake centerline may end up advanced, or at 106*, or retarded-depends on how accurately things were machined-Chrysler and Comp stuff is fairly accurate. if the cam is advanced=more low end, less top end. retarded=less low end, more top end. break in with the comp outer spring and damper, without inner spring
