Autolite 66 plugs on clearance at Rock Auto. .56 cents apiece.
I grabbed 16 of them. Great plugs. Play through.

The 66 plugs are what I have been running on my 318/360 small block, I wounder what is the difference in the 65s plugs.

The last number is the heat range of the Autolite plug Mike.
The lower the number, the cooler the plug is. Autolite 65's would be a tick cooler than a 66.
 
Champions
I see them in small block mopars when I buy a used one, my white 85 ramcharger had Champion plugs and it may have been the wrong temp but I put new NGK plugs in it and it was like night and day on start up, and my son said NGK and Autolite are the best for there stock cars. I understand the timing and carb and compression means a bunch but I have always been told they don't last.
But to be honest what do I know.
Thank you
 
So I got the Autolites with their stupid magnet.
If anybody needs a magnet with Vladimir's 75 New Yorker on it let me know, just pay shipping Lol

Anyways, upon further investigation of the spark plugs, nine of them were built in the USA, seven of them were built in China.
So I guess that means one of my cars will run right. :)
