That cam should build some decent cylinder preasure, it will not take advantage of the e-85s high octane and cooling ability but it will run very good and make a few more HP than pump gas just because of the extra oxygen in the ethanol. I would not be afraid to bump at least another 2 points compression, personally I like living on the edge and would add another 3 points.

noticed what i wrote wasnt realy clear, i will get my 2-3 extra points of compression from a litle 3.3liter twinscrew supercharger i also like living alitle on the edge this combo but with alitle more compresion ran pretty good on pumpgas not that long ago

It can make more power if you tune for it just because e-85 allows you to put more oxygen in the chamber witch allows you to burn more fuel witch makes more power. In order to get the extra power you will need to increase your jet sizes and advance your timing a little. I think at e-30 or e-40 you will not notice the differance in power because it will be small but it will definately help resist detonation. Even at 8 to one compression e-85 can make more power because of the extra oxygen but it really shines at the higher compression ratios because it is so good at resisting detonation and allows more compression, it does not need more compression to make more power but combine the two and look out
