I've been driving my entire fleet on ethanol fuel since it was mandated in Atlanta in about 2007.

The only problem it ever caused me was ruining the diaphragm in the original fuel pump in my 1956 Cadillac. After an ethanol resistant pump was installed, I had no further issues.

Ethanol is crap but if you drive your truck regularly you won't have any problems with it. The 235 will be just fine on 87 octane corn juice.

I've put over 3000 miles on my 1950 216 running on ethanol.
