Well since my dumb computer just deleted everything I just typed, I'll make it simple.
Regardless of FI or NA, you WILL need a rear, and trans work
You strayed Him to FI, after his second post he still wanted N/A
Reliability could easily be handled, the block itself is not the issue, rods/bolts are.
Him going 485 or so N/a is still closer to his original goal, then throwing it out the window and going with a procharger.
Iforgot the rest i had typed up, so I'll stop here...
And PS Vista sucks ***.....

485 is still a long shot in my book.. it can be done, many have.. but your putting a lot of faith into it... you could make that with 6 lbs on a procharger and other wise stock motor.. thats about as street friendly as your going to get.. wont even know its modded below 4500rpms..
and thats leaving a LOT on the table..
and yes, vista does suck!
do you have firefox or explorer?
Ha, and this is coming from someone who just a while ago would of swore 500rw couldn't be done on stock cubes. Now it's "it can be done but not reliably". The guys car that blew was just one of the several examples of a 500hp stock cube car. It's still one heck of an accomplishment and deserves more kudo's than doing the same thing with F.I. if you ask me. 
i dont think the OP wants to achieve 500rwhp for 3 track passes or 500 street miles... most people want it to last.. which from what i have seen, doesnt.. most 500rwhp procharged setups last for a good while..
besides, that would put him at 650+.. way more than what he wants for now.

Pat G's combo in the T/A lasted quite sometime before the car was sold. "Miami's" setup also stayed in one piece for an extended period of time as well up until the stroker build. Excerpt from him when the motor was taken apart: "NONE of the 8 pistons have any signs of contact with the valves, and I have recorded 9 over-revs to 7600rpm and an amazing amount revving to 7500rpm!!!! This combo rocks!"
So where are you getting this "3 passes and your done" stuff from? The facts speak for themselves. It can be done and successfully!

no 500rwhp NA car will seem even remotely stock.. it will be loud obnoxious a pain in the ***... etc etc etc..
500rwhp out of a stock cubed NA ls1 is near impossible.. have a couple people done it? yes... but your looking at BIG bucks and a HAPPY dyno..
you can have a BEAST of a street car and pull the tires off the ground at the track with 425rwhp (i do)...
if you HAVE to hit 500rwhp.. and you dont want nos and you dont think turbos are reliable..
GET A PROCHARGER!!!!! on a bone stock car @ 8 lbs (that is a safe amount of boost) you should be right at 500rwhp or a TAD more..
add LT's a cutout TB and you should be sitting pretty decently around 535rwhp or so..
reliable, VERY street friendly, etc etc etc..

Add sticky tires and that power is going straight to the ground and HARD.
So to answer your questions, 8 lbs through a procharger on a LS1 would be around 525rwhp or so. A4 would need stronger internals, M6 would need a better/stronger clutch, a stronger driveshaft would be in order and of course a rear end if you plan on actually running at the track, sticky tires or not.. launching with a 10 bolt and either M6 or A4 with that much power will be too much for the factory axle.

I disagree on the 383. Why would you not want MORE tq. EARLIER in the power band
I have also read on here you can't spin a stroker as high as stock cubes but that is myth. A properly built stroker (good rod bolts, good valvetrain) will handle the same rpm as a similiarly built stock cube motor. It will simply make more power EVERYWHERE provided there is no restiction somewhere.
Why the hell do you think there are so many 402/408's on this board?
I'll give you a hint....... It aint because because a stock cubed LQ4/LQ9/LS2 makes more power

D1 Well I guess its time to post on here finally.....anayways I run a stock bottom end 346, Ported 241 heads, 9lbs on a D1, motron 60lb injectors, twin walbro pumps, headders/exhaust, cam/ supporting valvetrain mods and a little more and make 580rwhp and 550 rwtq...so personally id say boosted is the way to go...make the power easier, and more "streetable"...with better manners all around lol

if i could build a setup right now from ground up D1sc would be hands down my choice..

Although I would go 402/408 anymore, some 383s really get the job done. My mild/budget 383 made 465/465 though a LS6 intake, undersized headers and with a smallish cam. It was tuned to be extremely streetable and take a wet 150shot (which netted about 650rwhp/rwtq) all day long. The torque "curve" really made the car a different (and better) animal than it was with the heads/cam set-up that it replaced.

there is one definate answer, bigger cubes would be your best bet, my old LS1 had heads, cam headerback, intake, throttle body, and a dyno tune and it barely reached 400rwhp.
i dropped in a fully built 427, it made 450rwhp with a mild cam, 1.5" headers, and an 85mm intake/throttle body, (both of which are too small), if i bump up to bigger intake, bigger headers, and a hot cam, with a new tune, i should hit 500rwhp N/A
you cant argue or go wrong with a 400+ cubes motor, thats fully built, if you have the proper parts witht the proper tune, 500rwhp shouldnt be a problem, after that you have unlimited potential with nitrous, or boost whichever floats your boat best.
