I have had good luck with NGK 4554 on stock SBC motors. Ive ran and still run autolotes for many years. Last year I experimented with a set of AC Delcos. I don't think the brand of spark plug is as important as it being clean and gapped properly. But there are many options on this subject.

I run standard copper Autolite 25s in all my SBC engines and have always been happy with them. However...iv'e purchased a set of Autolite Platinum 25s and a set of Autolite Iridium 25s that iv'e yet to try. Im a firm believer in "if it aint broke don't fix it" so i keep using the copper plugs cause i have good luck with them but id hate to have something better sitting here and not know it. Has anyone tried the Platinum or Iridium plugs?

I used to run Champion plugs in my Mopars until I started getting a few bad ones. I then switched to Bosch and AC Declo and I’ve had pretty fair luck.

Stock ignition I use plain NGKs. “Upgraded” ignition systems I use Iridiam plugs. I run Mopar, however I am building a SBC.
