Potential twin turbo build, looking for injection advise

Are you guys planning on using the stock block for these builds?

550 horsepower will be safe on a stock block but when you start turning that boost up you will be taking some serious risks. I looked into this for a while and it ate me up trying to decide. I knew I would want more than 600 horsepower out of a turbo set up so I didn’t go that route.

Just be conservative on the tune.
