Spark plugs for 305 third gen.
I have a set of 8 brand new champion 3018 platinum spark plugs. I had bought them for my Camaro,but then used some ac delco copper plugs. Someone had mentioned not to use these plugs because of the higher heat range and because they are not resistor type plugs.
anybody here running 3018’s? I’d like to use these in my car is there won’t be any issues. Beats buying new ones. Any advice is appreciated

It'll probably be ok. Pull one in a few hundred miles and confirm you like what you're seeing.

Re: Spark plugs for 305 third gen.
Those Champion platinum plugs are resistor type.
If the gap is bigger than .045" adjust that.
They are fine.
If you are going drag racing. try a Champion RV8c gap @.035"
