Interesting discussion.
How feasible is it for holly to design a carb that works with higher ethanol content? I already have stainless fuel lines, how big a deal would it be to upgrade the fuel system to be compatible? Yes its a PIA, no I don't want to roll over and capitulate, but if the gas isn't available it doesn't matter so might as well mod the car to be able to keep driving it.
BTW, I tore my 78 f-150 apart in military base housing, sandblasted and painted it in my driveway, and out it back together. Took about 2 months. Neighbors thought it was cool.
