High compression with aluminum heads and pump gas???????

12.85:1 and aluminum heads.........040 quench.
Runs like a dream on pump gas.
Of course , it's E-85.
96 at the pump in Brazil ?
How much a liter ? I definitely dig your style.
Much of Europe has 98 to 100 octane available at the pump too......but then , they tend to love their cars. ;-)
