I run 100ll in my 383 dart. I can’t tell you the differences in the fuel but I have ran about 60 gallons through my car with no problems so far, no corrosion or lead buildup on valves or plugs, and it hasn’t messed with my o2 sensor either.
But cab is right, your jetting is going to be different and maybe need timing adjustment, I’m one range colder than factory on the plugs, 38* timing locked, and the jetting needed to be leaner than 50/50 mix of pump gas and cam 2.... now if I could get my cruise afr right I’ll be golden!
