Are those what YOU run or what you're saying the factory recommends? Because .060 is an L67 as well.

Stock supercharged is .060

Being that it is common practice by members of BC with the L67 engine to gap their plugs at .055 to offset the effects of high cylinder pressures, I was under the impression that it was a factory specification. If that is considered by yourself to be erroneous information, then I will extend my sincerest apologies.

I don't think you owe an aopology, the topic is "What you run your gap at" not what is spec'd. I didn't even think you were trying to list specs

I run at spec'* w/o problems.

Specifying a plug gap or even a proper plug for his Trofeo based on his mods would be impossible. He has issues he needs to fix and properly tune before selecting the right plug/gap.

MACDRIVE, .055" is what L67'* use when they are one nominal pulley size down on plugs that are one heat range colder than stock. Lightly modded L36'* benefit from the same combination due to the higher compression ratio of the L36.
