"Another issue I have is It needs 93 octane or the thing will ping like crazy." ^^^
I run the Non-Ethanol in my roller 318, no ping...
A little more money but I don't want that ethanol crap sitting in the bowls of my edelbrock here in the salty humid air of Florida. That ethanol blend will pull moisture right out the air into the fuel.
Put ethanol out in an open air small can while working on a generator. The fuel in the can turned white after sitting open to the air after 1 hour. Yeah, it draws moisture.

Here is the Plug I am running in the roller 318. GR4 V-Power, it burned clean white after switching to the Mopar HEI conversion and E-coil. Has more of the porcelain and electrode hanging out than your N11YC.
