What plugs are you guys running in your Lt1s.
Im not sure the age of mine or really whats good for it.
I know the pcm has been re programmed. (for the fans i think an rev limiter?)
Has the cooler thermostat.
Slp headers full 3" exhaust.
K&n cold air intake.
Few other things done to it but there not motor related.
I have yet to find out if there is any internals done to it.

I ran the TR55s for awhile, but i feel there a tad hot unless its a just a DD & not too much thrashing in stock form, now i went with the TR6s, because i'll be running alittle juice, they are holding up very well NA, even in stop & go & cruiseing around, so i say get the TR6s, especially with bolt-ons., gapped at .035"
