Small Block Chevy plugs
These seem to be the right plugs for my 1970’s Chevy engine. Plugs came in with no issues and cheaper than the chain stores.

good plugs at a bargain
These are the best plugs for my 1993 Chevrolet k1500 with a 5.7 liter. I run a little bit of advanced timing causing a lean burn. Other brands will have the strap close as they get hot. These plugs with a higher nickle content will run 25k miles and still have plenty of electrode left. And the gap actually still be in spec. A few other brands I have tried get to about 10k before they are closing up or electrode eroding in my setup. Keep in mind I'm not running a hot rod. I'm running a 1993 TBI with over 200k. Its a little old and a little tired. Its not worn out by no means, but it's bone stock and that was always a mild motor setup. Put 30+ years on top of that I promise you its not burning any tires. But it loves these plugs and I'll keep using them. And at a few bucks a pop they are a bargain.

Shipped loose in a bag
Standard ACDelco plugs, inexpensive OEM replacement. My only issue is that I ordered 8 and they came in a shipping bag, so when I opened the bag, most had escaped from their protective cardboard boxes and were rolling around loose in the bag. Thankfully none were damaged significantly. I did have to re-gap a couple of them, but you should always be verifying the gaps on any spark plug replacement job.
