i run my 10's gapped at .025. - 12:1 comp on c116 spraying 200-250

 

I was thinking .022....I'm new to the LS world and not sure if that is too small of a gap or not.

 

We have run it as low as .016 in WhiteLTone's car, generally I like them from .020-.025..

 

I'd start out where Stroker and WhiteLtone run theirs around .022-.024.

LS coils have a pretty hot spark for what they are and can tolerate a tight gap.

 

Remember, bigger gap on the spark plug does *NOT* equal a hotter or stronger spark. All you are doing is spreading out the spark thus making it weaker, especially when adding added cylinder pressure to the mix.

Just food for thought.

 

As Martin said I would star around the .022-.025 range.
