Havent seen a post about what plugs to use for a CC305 cammed LT1 here. Did a search and didnt really find what I was looking for.

Basically I'm currently using the NGK TR6s when I was stock but was running a 75 shot. I have since installed what's in my sig and got rid of the Nitrous so what would be my best bet for Plug brands??? Should I stick with colder plugs and gapped at 0.35???

I'm looking for reliability, long lasting, and possibly increased gas mileage....

Looking for ideas and suggestions....

Thanks.

I always hear that the ngk tr55s are good. I ran autolite 104s in my car...but i think 105s or 106s would be better.

TR55Xi's have been quite nice for me so far, lil xpensive tho

there should be no reason to change the heat range of the plug unless you are running nitrous, forced induction, or change the compression.

Just picked up some Autolite 104s and will try these out, hopefully these will be comparable to the NGK TR6s.

I'll have to agree .....Help me reach the time in SIG.....Great plug......
