Pump E85.You didn't give enough details for me to make any sorta meaningful opinion on but I will say this, the right plug and the right coil makes it or breaks the fuel and I've seen it a bunch of times. My engine runs way better at 200 than it does at 170 or less. I'm often taping up the radiator to get to 200 even in the heat of summer. I'll also add a lot of so called E85 carb guys, even big names, are converting alky carbs to E85 and while it works, it brings it's own set of problems because its a different animal altogether. It's easy to get along with E85 but tuning it like gas/alky usually ends up in a bunch of broke stuff.
