    E-85 question

    I have been wanting to convert my g body to e-85 for some time now and was wondering if anyone here has experience with converting a Holley 4150 to e-85. I have the appropriate fuel lines and plenty of flow, but do I have to change out metering blocks? The engine is a very mild 350 sbc
