compression ratio vs octane

This type of stuff fascinates me and is what inspired me to go on to study mechanical engineering in college (which I hope to do after high school). My ultimate plan for my '70 Duster is an aluminum Edelbrock Magnum-headed 360 with around 11.5:1 compression. If dgc333 could use pump gas in his 10.6:1 iron-headed 360 Magnum, then I probably could too with 11.5:1 compression and aluminum heads. I might even try TBC's and will probably work the chambers to round off any sharp edges. Of course, that's all if modern Hemis are still expensive and hard to find by then.
