Buick V8 on Ethanol

Victory is MINE 
My '68 Jeepster is megasquirting Ethanol
'67 Buick 340. I used a V6 distributor housing with Chevy V8 guts to use a 7 pin HEI module.
I'm also using the MS&s extra input mod.
Chevy 4.3 v6 throttle body with stock v8 injectors, also using the idle air motor.
Running a Ford external fuel pump out of the junk yard, pushing about 12psi
I built custom long tube headers with o2 bungs, and I'm using a narrow band
So far I'm doing well, getting the same milage squirting e85 as I was carbed on gasoline,
BUT! it's still a shade shy of 10mpg
Probably due to the 33" bias ply tires, 3.73:1 axles and a TH400.
