110 Octane and Timing

I had a 340 with eddy heads, crower solid 253-258 and 525-530 (i think). with 10.5 KB with BM 2500 727 and 3.91 and 245s in the back. I beat the hell out of it on the street and never got it to a track or dyno. I tried running a lot of different fuel mixes and tunning. 110 didn't seem to pull any harder or char the tire any longer. I did seem to idle smoother though.

Best thing about it though is the smell!!!
