Another reason I forgot to mention is 87-93 octane pump gas has 10 percent ethanol. I know ethanol burns hotter and I just wouldn't feel good if I put it into the tank. I guess I am paying extra for piece of mind.

Your peace of mind is what's most important.

We usually have the ethanol mix here too, but I'm running it in a 10.2 LT1.

What are you paying for 110? Here, at the racetracks, leaded is $7.50/gal or higher.
We also can get 100 leaded here.

Many years ago, I ran my '63, 360 HP all the time on pump gas (leaded hi test) which was maybe 93 - 95 octane. I ran it that way 4 years as a daily driver and pulled the motor apart w/ no evidence of preignition. 11.25 C/R.
