Although some of the supercharged Verado's require higher octane fuel, the FACTORY RECOMMENDED fuel for all E-TEC's, except for the Military versions designed to run on JP-5, is 87 octane! And all the big block motors have knock sensors that will put engine into 1200 rpm limp home mode if you DO happen to get a load of bad gas, such as phase separated E-10 that's lost octane because water absorbed all the ethanol!

I concur with Terry and the others regarding repowering, as I went through the same thought process when I repowered in 2006. Although my overall average gas mileage went from 2.8 to 4.4 mpg by upgrading from 1975 technology, I could still buy many years worth of gas for the $12K or so it cost me to repower! The only way to really justify it is the clean quiet reliable operation of the new motor! And I have to admit that the dozen or so nice trips I've made with the new motor probably would not have happened either!
