I would go with the FT crank. Forged cranks are great if you can find them. I know some aftermarket suppliers are making new forged cranks, but I haven't heard enough feedback from them yet. So if you wanna go forged, you're left with the 427 $ cranks or the FT cranks. Since yours has already had the snout and flywheel flange machined, you're good to go. Plus the weight is really good for a forged piece.

As for the rods, I would go with an H-beam rod. You'll need the extra strength that an I-beam won't provide at your power and rpm level.

To help your engine rev, don't forget about the lightened valvetrain pieces.
