gap for plugs - MSD box & dist.

I’ve gone further on a driver. A stock low compression 360 looking for mileage. When the gap was at .055, it fell off some and I went back to .050. This is what I found best for THAT APPLICATION which may it be good for YOUR APPLICATION.

With the higher compression ratio, the gap needs to be smaller. IMO, that .045 is correct and what I’d run and do run as well.

Same spark plug by the way.

I also have no issues with Champions. Others like Autolights a lot. Some claim they last longer in the race or hotrod. I’d just run what ya got. No trick plugs needed.
