I run a mildly built 383 Stroker in my Drag car. About 450-500 HP. Which spark plugs should I be running in it?
Which Spark Plugs are the best?

Friend used to use Champion in his 440, don't remember the story but they were all bad. They were the racing plug and when he go in touch with the they tried to blow him off. He told them to look at their stock and sure enough the ones they had were bad too. Wish I could remember what was wrong but you could see it with your naked eye. They were being made in Mexico. He got a whole bunch of free ones for pointing it out to them.

The old guy that taught me how to cut cut down ground electrodes said NGK had the best metal in their ground electrodes as far as shaping them goes.
In a pinch I'll do out of the box Autolites but usually, I buy 4 or 5 sets of NGK's at a time and get to whittling on them with a 1" belt sander.
I asked a couple of the crew guys in a Pro Stock pit if they would mind if I looked at an old spark plug just for the hell of it. The guy was cool about letting me look, those guys really do a number on them.

They narrow and shorten the ground electrode considerably.

Remember when NGK race plugs had a gold coating? Then they went to the silver coating that is not as easy to read as the gold. I wonder if that plating change was a heavy metals environmental deal or if it was because they started making them in another country?

Kind of, look at the ground electrode on an Autolite race plug and the strap is shorter.
Some race teams narrow it as well as give it a cut back on the top. Hard to say what it's worth in HP on a dyno.

We had a batch of those gold NGKs, kept fouling. We suspect they were counterfeit!

Looking at the Brisk site and cross reference to NGK. Did not see a Brisk equivalent to a R5671A8 or 7 or 9. 5/8" hex, .750" reach, gasketed.
Anyone got those crosses?
I assume the Brisk Silver Race plugs would be pretty expensive.

Never heard of anyone narrowing a strap. Cutting them back to expose half the center electrode has been a "thing" for decades. Most of the non-projected race plugs are already like that from the manufacturer.
I would think narrowing the strap would potentially cause them to overheat and possibly melt.

They look interesting but NGK and Autolite AR RACE plugs work great

Those Autolite AR plugs are what I use but NGK is excellent too!I've also heard of some cutting the ground strap completely off ?
