I like to use the Autolite 5224's in a stock motor or the Champion 436's. Make sure you use only a copper core spark plug. These motors do not like a platinum plug no matter what the parts guys try to sell you. If you have some performance work done to the motor and are experiencing any spark knock then I would suggest switching to a slightly colder heat range plug.

In my race motors or ones that I build for some hot street applications I use the Brisk spark plugs. A Brisk spark plug that is comparable for your 360ci Mopar would be the LR17YS-9.

I use recommended OEM stock Champion RC12LC4 copper plugs. They seem to work fine. A lot of guys recommend the Autolites mentioned by Fast69Mopar and experience better idle and throttle response from them. I haven't tested them personally.

Just a bit of info, the Champion RC12LC4 is the Mopar part number and is the same as the Champion 436.
