How to build a 13 second 340 Duster

More than octane around us in CT is the ethanol mix they run. It's currently 10% for the entire year, but in addition to that, between November and February, we also have other additives so the moose in Maine can breathe easier. There's too much involved witht he engine package IMO to base a buildup soley on static compression. I have 10.8:1 iron head engines out there running fine all year, and I have 9:1 iron head engines that tuning for this fuel is a headache. All depends on the assembly as a whole, not just piston and head material.
