plugs ?

3.4 sc pully, not sure witch plugs to use.any advise?

read the first first post titled "97-03 FAQ, Perf mods, common fixes read first ". It will answer most of your questions.

Please tell me you have more mods than just that 3.4 SC pulley, But to answer your question, Typically GTP guys like to use Autolite 104's gapped @ .055

What other mods do you have?

borla catback,u-bend delete,180t-stat,fwi,dhp pcm,3.4 pully.the plugs im using are laser iridium longlife heat range 4. iwas told to get colder plugs.

Here ya go: Why Autolite for GPers

I'd throw a bigger pulley on there while you're at it

I've got to agree either get a few more mods or go to a bigger(3.6") pulley I would suggest at least a plog and 1.9 rockers or a overkill tune.Chico(pops)

i apreciate the advise.whats a overkill tune?
