I believe there were some Edelbrock/Carter AVS 4bbls several years ago, calibrated for E85. Holley's had their anodized models of late, which I figured would better tolerate the E10 and such (but not sure if all surfaces were anodized, including the internal passages) and I do recall their E85-calibrated carbs.
In the 1990s, when fuel octane boosters were prevalent, there was one additive which stated that if it was used "full strength", then you needed to upsize the jets by 4 sizes. We figured it had a lot of alcohol in it.
There are many upsides to ethanol, but all that is good about ethanol is just as good with butanol, possibly, except possibly the production price . . . although butanol had NONE of the negatives of being in an older fuel system. Be that as it may.
It seems that most of the older vehicles which seem to have the least problems with E10 (other than deterioration of rubber lines, diaphrams, and such) are those that see regular use.
And I also like domestic, USA-sourced, gasoline, too.
