Amsoil Z-Rod for cammed LS3 w/cats
Im running American Racing headers with the cats they now supply. How long should they last with Z-Rod?

You will be fine. They will most likely outlast the engine.
The theory of zddp harming the cats is a statement that has to be made mandated by the epa, many folks say they have never experienced issue |

For a cammed LS3, would the Signature Series suffice, or must one switch to the Z-Rod? |

1. For pure racing and better protection, specially for large cams.
http://www.amsoil.com/shop/by-produc...code=RD50QT-EA 2. For racing and street driving. http://www.amsoil.com/shop/by-product/motor-oil/gasoline/z-rod-20w-50-synthetic-motor-oil/?code=ZRFQT-EA 2. Another good option is the Euro 5W40, there are a few 1800 HP GTRs using it. http://www.amsoil.com/shop/by-produc...?code=AFLQT-EA |

Andy, for Racing and street driving, am I reading correct, that you recommend 20W/50??
Isn't that a tad too heavy? |

you should NOT run 20w50 in a LS motor. z rod 10w30 is fine.

Remember the key point here is that once your engine is built your engine builder will spec an oil viscosity,, he should not mandate which brand of oil but which viscosity. But if your block is stock then Sig Series 5W30 or Zrod 10W30 even better |
