recommendation for spk plugs 02 ram w/360

Good old stock champions.
Those engines don't like the iridium and the platinum plugs.
Do yourself a favor and replace the cap and rotor and buy the "better" grade wherever you buy from. The cheaper ones have aluminum contacts, the better ones have brass ones. Brass ones resist corrosion much better. Especially if it sits a bunch as you say. And the price difference between those isn't that much either.
I have an old cap from a 360 that was towed to me cuz it wouldn't run a couple of years ago. The coil tower on the cap is completely burnt out, carbon arced out of the center of the cap. People still laugh at it when I take it from the top of my tool chest and show it to them.
