For E85, I would do -8an and -6 PTFE lines, good stainless element filters, a good regulator and rails, and at least 80lb injectors. For the fuel pumps, do either dual AEM E85 320LPH pumps, or a MagnaFuel or Aeromotive Elminator.
If you could get the 6.0L I definitely would, what year is it? Do head gaskets, head studs, at least a TU1, Tick Stage 1, or BTR/LJMS Stage 1 Turbo cam, and an S475 or S480.
As for the rearend, a Quick Performance 9" is semi-cheap, and very strong.

Wish I coulda thought of that, I'm asking for what to look for in a turbo cam. Besides just seeing what others are using so I can learn how to build a turbo motor more indepently down the road. Sorry I want to learn these things with from you "helpful" guys here. It must be so hard to teach anything to anyone. I have been looking at the Tick Performance Stage II Turbo Cam and may be able to get my hands on a set of 317 heads for $150
Ok, you can cover that goal rather easy. Check my 2012 build link in my sig for part numbers.
5.3 or 6.0; just less boost w/the 6.0
-s475 t6 1.10a/r -- $640 (nothing wrong with the On3 but this turbo leaves you room to grow)
- the stock 862 heads are fine (unported). Lap the valves in with new yellow or blue springs and run them.
- ebay head studs ($70 ish) with LS9 head gaskets
- since budget try to find a ls6 cam cheap
- for me I like the cx racing intercooler kit w/meth inj and 93 pump over e85 but to each his own.
We have done similar 5.3's in the 550 to 600whp at 12 to 15 psi many times(even with less turbo).
Good luck.

If you have any questions about a camshaft for your engine, or any other items pertaining to your build please feel free to give us a call!
We would be more than glad to assist you with your build.

You asked for a suggestion and I gave you one. My suggestion is valid as a LS6 cam will do but if you want to ask for more details I would defer you to Lil Jon or Martin as stated above. Both of those gentlemen are super helpful and willing to explain things in a bit more detail.
Now back to your build....no need for 317 heads for your goals, 862s will do. As stated above by Malibu, add some springs (another option if you want to spend a little more are Comp 918, PAC 1218, or BTR) and you should be good on that end. Ebay head studs and intercooler is the way I chose to go as well.

No worries.
More combustion chamber volume, 317 = 71cc 862's=61cc (may not be exact figures just copied off a site) further decreasing compression on a 5.3. With that being said, most guys would not recommend running the 317 in stock form on a 5.3 because they say its sluggish off boost and reduces low end power. I have not driven that setup personally but if you ask around thats the consensus.
I have seen a few guys run the 317 and like them but only when milled approx 0.020-0.030. I am sure others with real world experience can chime in.

I agree, 317's on a stock 5.3 are not worth the trade off (sluggish off boost due to the compression loss stated above). And dont mill and OEM head on a boosted application. You are only increasing the chances of lifting the heads because you are making the deck thinner on the heads.
With that said the 317's are one of my favorite stock heads and definetley worth having a set (or 6) laying around. They flow really close to the 243 heads and have one of the thicker decks of all the OEM heads so are more desirable for boosted apps that reason too.
On a side note, you could get your 500whp ish goal with a stock cam with enough boost. But if you can squeeze $400 to 450ish extra out of the budget for a custom turbo cam (from Martin or lilJohn), you will be that much ahead of the game down the road and the HP will come much easier.
