First off, I hope you all had a Happy Thanksgiving!

I have come to a crossroad here that I am having some challenges with. I currently have a 400/500 230 thick main engine with SR's, and roller valvetrain. Recently, I tok it apart and noticed the cylinder walls scored pretty bad. If the block doesn't sonic check, do I continue down the B block road, or sell all the BB stuff and head Gen 3. I have a line on a 6.4 SRT motor and trans right now. It's just going down a completely new road. Anyone here ever been in this situation??
