I think most of them can run E-85 as long as they have injectors that can handle the extra flow rate for the HP level.

The '71 Charger has the Fitech Go-EFI 8 PA (1200HP) TBI. it has eight 80# injectors in the throttle body. I think on E-85 it could support about 800 HP?
Currently running 100 octane gas, but upgrading the 340LPH fuel pump to a 450LPH E-85 Walbro pump to run E-85. Engine is 12.4:1 compression.

I just got a Sniper unit for my 360, but no plan to run E-85, although it says it can. It only has 9.5:1 compression.
