Default Lets build a 408ci + Turbo

So as the title states I want to pick your brains...!!

Lets make paper build that in perfect situations will produce 900-1000 rwhp
Starting with a 408 ci short block, lets put heads, intake, and fuel. Then we will need to size the turbo and all piping.
I have read some about the turbos and setting them up but know next to nothing about doing it because ive never done anything with them.
I know its more than enough motor to do it but my thinking was to not have to boost as hard and make the engine last longer.

I made 955RWHP at 22 PSI. Stock cover cast wheel. I would also suggest the race cover. I will more than likely be switching to an 84mm billet wheel and V2 race cover. That should be enough to put me well over 1000 if i want to push it.

For only 900 rwhp goal a stock strong rod with a JFR cam will do it with studs and gaskets
