Re: Code PO327, PO430??? Did you cut your cats off or any other mods. This could explain you codes. if you did you could fix it with O2 simulators and a MAFT. just a thought.

Could 430 be an O2 sensor? I might try swapping out the passenger side O2 sensors with new ones from my '02 Z28. What do you think?

Re: Code PO327, PO430??? Yes 430 is the right bank sensor 2. That is the one behind the cat. Before going to all that trouble, did you run a O2 system check? Might be worth the trouble.
