If, after carefully breaking in my solid flat tappet cam, choosing reasonable ramp rates, high quality components, always using Brad Penn and adding the original GM EOS supplement, plus sending my oil off to check the zinc/phos. content (which usally came back over 1500ppm)... if I wiped a lobe/lifter I would indeed throw in the towel and use a hydraulic roller. But I believe that quality components, reasonably ramp rates, and high zinc/phos oil will let your solid flat tappet cam outlive you. I don't know what would be in the current mix that would cause otherwise. |
