What spark plugs for a naturally aspirated 415 ci?
I'm building a naturally aspirated 415 ci L92. This will be max effort drag only setup. I ran the popular NGK TR-55s with my old setup, which was a practically stock engine. I'm sure with the new setup, will require a different plug. What do you suggest? Thanks.
