So you think going with a 9" radial would pick up the ET?
I think you'd gain a bit from a smaller tire due to the weight alone, and moving to a radial has proven worth the switch from what I've seen.
You have a lot of good suggestions here that will help, one good thing about swapping to ethanol is you don't have to tear into the motor. More than one way to skin this cat so it's up to what route works best for you.
