LT1 - What brand / type spark plugs?
LT1 guys.....
What brand and type (platinum, regular, iridium, etc..) of sparkplugs do you use / recommend in your LT1?
I was running Delco Platinums, but know they are not the best, so I am wondering what everybody uses.
Car is N/A only with no N2O or boost. Ill post my sig for the engine and car details.
Thanks in advance.

I was running NGK TR6's in prep for nitrous, but I'm holding off on the juice for a while so I switched back to either Delco's or Autolite 103(?)'s I think.
Since you're not going to be running spray or boost, I would recommend a platinum plug. Stay away from the multiple electrode ones, just run a standard Delco platinum and you'll be good to go.

I ran Delco platinums in my 95 Impala, only used 2 sets with over 150,000 miles ....as the platinum wears slower than copper....you'll get better conductivity and spark overall from the copper plugs....TR-55's are the way to go.....just depends on how often you wanna change 'em........

I never ran anything other than TR55 in my 94, and it is what I plan onrunning again once I get the LT1 in the 86. It is not that hard to take an hour out of your day every 10k miles. Plus, they are only 1.75 a piece.

AFR recommends these as starting range for their heads...

Haven't fired the motor up since I am still putting it together so I don't have any real experience with these plugs, but it is the recommendation on the AFR site.
