Not sure which plugs to run in my ls7.
I've always ran br7ef but this ls7 has square port heads. Not sure if they require a different plug then the cathedral heads.
Ill be running no more then 20lbs.
Intercooled? What fuel? I say throw some b8efs in there. Then again I've been accused of running too cold a plug before, but I'm also non intercooled E85 on 16-17psi.
