Today’s ethanol gas in carburetors

I've been running 87E10 since 1999 with the same fuel system, but several different carbs, none of which have had a problem. I did start with a new tank, a new 3/8 steel line, and a new HO pump. I fabbed a 1-piece line from pump to carb. At a jobber,I found a large EFI filter that I installed at the back, just in front of the right front spring hanger, that I have never yet changed. There are 3 EFI hose jumpers; one at each end, and one at the filter. The filter has one screw-in connection, IIRC, on the inlet side.
She has sat every winter from September to May. And has accumulated over 125,000 miles .
I built the engine to specifically use 87E10, with an original Scr of 11.3 and aluminum heads.I thought 11.3 might be borderline high, but with the 292/108 cam, it was no problem. Later cams have run 10.9 with a gasket swap, and a decking. The Dcr remains about the same at 8.7 corrected to 900ft elevation.
The carbs I used were; Big Thermoquad, and three Holleys. 600VS,750VS and 750DP
Your results might vary, but really shouldn't.

PS, forget the 600 on a 360,lol.It's a real power-choke. She's just my mileage maker that I bolt on for long trips.
