I'm starting to kick the idea around in my head but I don't want to wish I went with a forged later on down the road. It's a street car that might make 6 trips to the track a year.
If you want to keep upgrading the power, better off with a forged crank. I figured since i would never exceed about 500 hp or 6500 rpmthe cast one was good enough. Hopefully I will have an answer on balancing cost shortly, which might help you out.
