Changing spark plugs in a small block 360 Any recommendations on which brands are the best to use?

How much do you know about spark plugs? As in.. what do you know about plugs that leads you to believe there's an "upgrade" and what does "upgrade" mean to you exactly? What don't you like about the champions? Are you trying to find power in changing spark plugs..?..
if so , stop wasting your time.
Go play with the distributor timing and advance... that can find you more power.

I’m going to tell you a little story about Champion spark plugs. I’ve told you guys stories about the 1970’s and how we street raced almost nightly. Well I had Champion plugs in my 340 that a local Mopar engine builder built for me. After I had 600 miles on a set of plugs I had to make a 3 mile drive to a hill that I still climb almost daily. I had to go down into Freeport and when I climbed the hill I had to lug it down in third gear and jump on it. Boom boom it would backfire twice every day I did it then it was race ready. Well I asked the engine builder and he asked Champion spark plugs. Yep. Well throw them away and get Autolite plugs and gap them at .028. It never backfired again. Hmmmm
