50/50 mix of ethenol and 93 octane yay or nay?

I have an 83 mustang with the following specs... 302/315 lunatti stroker kit, a b&m 144 roots blower with 10 psi boost, 750 cfm holley double pump with 50 cc pumps, msd ignition, trick flow aluminum heads, holley volume max racing pump, 1/2 inch aluminum fuel line ect.... Too much more to list. So my real question is, can I run my race car on a half and half e85 mix with 93 octane?
