like stated above once you get to 500hp your gonna want 600hp and keep going on from there thats why i went and purchased a street bike now i want to put nitrous on the bike 
my goal is 500 rwhp with my procharged lt1 im going to stop there for now and save up for a forged bottom end and some other goodies 
let us know how it goes i will post my dyno results in a few weeks good luck

Now for tuning get tunercats..very affordable and easy to use.
Get some 42lb injectors and a 255 pump and be set on the fuel.
One other thing that can be an issue is valve springs.They are not strong enough to close the valve with enough boost and rpm.Thats pretty much it.Run an intercooler to stay away from detonation and be set.

I used to have that cam in my Nitrous setup. Loved the cam. 12.0 on motor, 11.1 @ 121 on a 100 shot. Do you have a video of it idling?
Here it is in my car back in 2000

im making 650 whp with 2 bolt studded mains with arp bolts, stock crank, and eagle forged h beams and srp forged dished slugs ~9.0:1 compression. But ive aslo got ported heads and a 224 236 cam. Who knows how long it will last for, but id say if you ran a similar short block, got a d1sc head unit and fabbed up a ebay fmic youd make 500 pretty reliably.
