FWIW I've run the E85 (not this motor) at ~1.10 lambda at cruise with good results. On this motor anything less than 4000 rpm is still on the converter quite a bit so I can run it a little leaner down there. Obviously doesn't help the mileage with this gear/converter though. I was getting 13-14mpg with a t56 and the same gear.

I used to get 21hwy and about 14 town with my 87 buick 6.0L, 76mm, 4l80 and 3.08 gear on E85. On gas it did 18/26 or so if i was very careful with it
Running in standard AFR it was 15.5 at idle, 15.1 light accel and 16.5-16.7 under regular cruise. Under high loads N/A up to 4psi around 12.2:1, at 8psi it was around 11.8, 12psi 11.4
You can run this stuff pretty lean with no problems, that car also ran 26" tire and a 3200 stall
