You can upgrade rods and pistons along with some fuel system upgrades and get even more power. My plans are to take my stock LS1 and upgrade the pistons and rods and shoot for 650 wrhp. The stock crank is said to hold 800+ HP without any problems but the rods and pistons are not up to par.
Im still a good ways from building the tubo setup but I have lots of ideas. It would be nice to see someone else go through this before me so I can see what kind of problems you run into. LOL
