I'm just wondering what spark plugs there running in their Hemi.I was running Ac Delco R43X65 but can't find them anymore. Thanks for any help.
What compression ratio, what fuel are you using and is this a street only or street and strip or race car only?
Hemi motors are all a little different, depending on the builder and application
BTW, I use to build, race and drive gen 1 and gen 2 hemi on the street and drag raced them also, I'm considering building a using Gen 3 now on a street project
My message is all three are different motors and do not like the same parts or tunes
