If you want to spend the money would go with Manley's I beam or other similar rod if you want to build it once to last at that power level. I know a few guys running the Oliver and Pauter rods, they're pricey but they're strong as hell.

I would stick with either a 8.5 or 9.0 CR piston, in case you ever move away from E85, 10.0 is not going to be too happy on 91-93 octane.
