168 is pretty toasty for pump gas, but no biggie for E85. E85 likes heat pump gas doesn't. I agree with Josh that you should consider a flex sensor and running a blend of ethanol. You also would be better off porting the supercharger vs smaller pullies. Especially if limited to pump gas.

For example, on pump gas you need to pull timing around 132 degree air temps or you will get knock and be limited to 17-20 degrees timing max depending on fuel quality.

On E50+ you can run 26 degrees timing even at 170 degree air temps and the engine is happy.

A lot of people to this day still don't understand Ethanol fuels. It's like liquid intercooling...no amount of air to air intercooling or heat exchangers remove heat from the cylinder as effectively as E85 does.
