E85 Plug Gap?

Hey Guys - I have a 455 Pontiac with E heads and 12.5 - 13 to 1 and E85. I have MSD 6AL, Billet Dist, Blaser 2 coil and Firecore wires with NGK's #7 gapped .028 to .030 - Ignition locked with rotor phasing adjusted.

What is a good GAP for this Plug Set up?
Thanks, Again, Craig

Thanks Again, Craig

Re: Dimpling Plenum Floor?

Hi guys,
Thanks for the input - I should have said that this is a drag race street - strip under hood with an air filter motor.
All input is welcome.
