Cranks

I want to run around 12.5 to 13 compression a good aftermarket rod and thats why the crank question I have the OEM crank and the machine shop said it was good but I'd like to try to hit 550 or so HP. I've got a lot of homework to do.......

If you run that much compression, I would agree with using a forged crank. But I'd start worrying about the main caps. But that's just me.
If I remember correctly, Mopar uses their beefier aftermarket blocks on their 450+ HP crate engines, and they have less compression.
