What plugs to use

[Slappy]

Thanks for any input. I am building a 360. Running 10:1 comp just under 500 lift cam , aluminum edelbrock heads. How do I know what plugs to use? If I go to the parts store they just want to sell me the stock spark plug. Not sure about selecting the right one.

I like autolite race plugs 3924.

You might be able to use the 3923 colder plug also.
They have a cut back electrode and are a nickle case plug.
The silver color of the plug helps with reading it for jetting the carb.
