110 plus 75 dry shot safe?
aslong as you retard the ignition timing you would be safe even on 93oct. with the right fuel pressure. i have done it on a stock ls... 110 would help yes, but isnt really needed.
and honestly the cost of 110 isnt really worth purchasing just cause. now if your car needed it then that would be a different story. but just to do it? it isnt worth the cost. but thats just my opinion. 
only thing i see being a plus by running it with your set-up, is having the "race gas" smell
