Hi all, anyone got shorty sparkplug numbers for a 73 340?
Also (sorry, I know spark plug conversations are a pain) i'm running headers. When I changed plugs last time the 2 that are "boxed in" by the header (driver side rear) were very dirty. I do have slight detonation under power even with high octane + octane boost, I'm guessing its one or both of the driver side rear cylinders based on the dirty plugs. The other plugs looked good.
Any thoughts on running 2 colder plugs in the driver...
