As long as it's built(all forged) and good head studs and gaskets ,you can run pretty much what you want or need to make the power your trying to hit.
Put a good set of cams and ported heads on it and you can make big power without to much boost.
Look at my sig.
That's only 16# of boost with 16* timing.
What kind of supercharger and are you having the tranny built?
Your tranny will be the week point with a big power built block.

If you have the L stock dual fuel pump set up, there good to about 450 or 500 rwhp. Most guys upgrade them to twin 255 pumps.
You may need to upgrade the fuel rails if going higher then that too.
I run 60# injectors and there good to about 700 or 800 hp.
When I run nitrous I'm hitting a little over 700rwhp.
I run a big air 3000MAF. You will be good with a SCT big air 26 or 2800MAF
At about 15# boost the stock Eaton is about at it's limits.Around 16PSI it starts making more heat then power.
You know that stock tranny will only last you a very short time at that power level.

k looks like im gunna stick around 15psi or less till i upgrade the sc......
yeah i know the tranny will go fast id really like to put a manual trans in there but i think ill just build up the auto....
thanks for the info about the MAF though
600HP(at the crank) is a goal if it takes me putting everything in then upgrading fuel system and later the sc then ok doing a lil at a time is fine but thats my end goal
Once again thank you for all the info!!!!
