I've put 93 octane, 10% ethanol fuel in every LS1 that I've owned for the last 17 years; cammed, stock, tuned and untuned. So yes, yes you can, absolutely, unless something about your setup requires race fuel.

Yes lower octane usually runs worse due to pulling timing, most notably if you have mods or a tune.

And gas with ethanol won't necessarily run worse, it will just get less efficiency than pure gas.
