I read somewhere that copper plugs are better for SC engines. Is this right, and if so then what plugs would be a good choice for me (not planning on extensive mods)? NGK are popular, do they have copper? I ran AC Delco Rapidfires on my SSE. I'm not planning on Bosch. Thanks!

Copper takes better to the extreme heat from the boost pressure.
NGK and Autolite are good choices.
I'm running Autolite 104'* (2 ranges colder). They have been on for over a year. I just had them checked and they look fine, no fouling or anything.

Yessir. NGK V-Power TR55'* are excellent plugs. Gap at .055" with a stock pulley (L27 and L36 should gap at .060"). After you pulley down to a 2.5", you MIGHT need to run TR6 (2 heatranges colder) in the summer. TR55 is one heatrange colder than stock.

I love (My cars does too) my Autolight 103'*. Really you can't go wrong with NGK'* or Autolights. I've had better exp. with Autolights then NGK'* but NGK'* will last longer. I guess it really comes down to $$ and if you mind changing plugs.

Pete..
Advance carries them as well. You could do them this w/e.
Got all the necessary tools.
For you: ratchet, extension, plug socket and gapping tool
For me: chair w/cup holder, remote for radio, and beer.

They should come pre-gapped to .055", but make sure you check 'em. I do mine with the strut bar in place, but some prefer to pull the bar for easier access. I've also heard it'* easier to do the rear from below on ramps, but never tried it.
