YOU are not going to meet this goal. I am not saying it is an impossible goal I am saying that YOU wont meet it.
it is possible, but lofty..remember to build a high rwhp number, you need a drivetrain setup just as well. go for a flywheel #, or a track time, but remember some high 9-sec lt1's are putting about 450-470rwhp down n/a. its possible, but would be a ridiculous setup.
with the 7.9x ls1 car n/a, I'm at least shooting for 8.9x n/a next year..we will all have our fun.

very rough ball-park idea below
engine (reputable mach-shop several sponsors on here, I like LME) $7500
heads (yada yada like above) $2000
bulletproof clutch (like McLeod) $1200
built tranny (recommend T56Rebuilds ...Joe) $1500
custom drf-shaft w/1350 uj's front/rear $400
custom 12blt or 9" - $1700-2500
dyno-tune - $400-500
$18,000 - 20,000 (including odd and ends like tubular Kmem, upper/lower A's, Heavy duty Torque Arm, etc, etc.

haha..just kidding guys. 
STS Turbo STS makes a rear mounted turbo system with 12lbs. of boost. It says that they put down 600 RWHP. Here is the link to their site: http://www.ststurbo.com/lt1_12_psi_dyno

like you said to each their own
Are you looking for a daily driver or a strip-only car?
And just how important is reaching 500rwhp VS what you are willing to tolerate as far as drivability.
Sure does make good bragging rights though

Make NO mistake, a 500 rwhp of ANY form will be a money sucking, parts breaking animal just to keep it up AFTER you get it built and the bugs worked out of it. Unless you baby it around to cruise nights twice a month.

Come to california and go to CSM race engines... steal my engine off the engine stand that's in the back.. it'll make all of 500 RWHP even with a power sapping TH400 and 9" out back..... better yet go to Texas and steal tony shepherd's motor..... same as this one pretty much and already made 535 with TH400/9" combo.... naturally aspirated....
Seriously though it can be done. probably not with the LT1/4 intake and definitely not with anything shy of 210's IMHO.... I think a 355/383 with converted single plane manifold, rock solid bottom end and AFR 210's or 227's fully hogged out with about 11.50:1 CR and up will do it.....
You can expect to pay about 12-15K easy for a motor similar to these two examples....
HOWEVER, keep in mind that RWHP #'s and getting over 500 is about the combo. you're going to need serious fuel system, stock PCM will probably need to be dumped for something along the lines of BS3, XFI, Gen VII, good cooling system, strong ignition, etc...... So you can expect the full out deal is going to cost easily 20K...... I'm estimating when all is said and done for mine i'll be looking at about 30K..... that includes suspension, fuel system, engine mgmt, tranny that can stand up to 800+ RWHP (my motor is setup for a 400 shot) and all the other odds and ends that I have bought IE vacuum pump, low mount alt kit, painless wiring harness, full cage, etc..... if you just want a 500RWHP NA LT1 it can be done for cheaper but you'll break parts pretty easily unless the ENTIRE setup is capable of handling that power..... can't have a 700hp LT1 with a 22 dollar pep boys coil if ya know what i mean...
