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

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)
