Ethanol or not Going to be firing up a new LS3 motor with cam and headers for the first time. Just going to run a few times before getting it tuned. What is the better fuel to use 93 octane with 10% ethanol or 91 octane ethanol free. These are the choices that are available in my area. Thanks

It's a stock compression LS3 with only a camshaft mod internally. So thinking the 91 ethanol free would be a more "stable" gas for now but would you switch to the 93 with ethanol when I do get tuned for better HP potential or would that not matter? Actually the 93 with ethanol is lower priced.
