If you're on a budget the stock shortblock will be fine But at the minimum you will need the following for 14-15 psi on the YSI.
-ARP Headstuds
-New set of Head Gaskets
-Probly Injectors
-Walbro 400lph pump (should be a Direct Drop in)
- Stainless Steel Exhaust Valves & New Valve Guides (This is most important for you)
- Dual Nozzle Meth Injection or E-85 (A Must at that boost level because 11-1 comp)
- Fluids
- Tune
- 3.25 8 rib pulley
That should all come in less then $3,000 to get to your desired power level if you install yourself.
At that boost level you should be around 850whp + or -

plenty of LSX blocks have been fine.. only a few have had core shift issues. You only hear about failures though.. no one evers posts "40k miles on my LSX and no problems!"

Yeah I'm not chasing hp numbers. 800-900rwhp will be more than enough so prob leaning towards a resleaved ls7 block or rhs block.

rule of thumb is if you want 900 hp.. dont build for 900.. build for 1300...

You dont need a ls7 resleeve if your making 950-1000rw, Ask me how I know.. 
Not saying its not the way to go but if you plan on making 1500+ then go LSX iron..

A couple 800+whp stock short block LS7s here for the non believers.

If your goal is to stay under 1k whp in the long run, I would just do drop in pistons and use the stock forged titanium rods.

When I do my set up it will be stock block and E85 until I have the funds for a built motor. Everyone on this board does not make $80K+ a year and can order a $15k built motor like they are ordering a pizza.

800-1000 should live on a good tune/good gas with decent pistons. If you want 1000+ I would look at sleeves/lsx/rhs. For ~900 then what he is suggesting would work great.

I really don't think I have seen many disasters from over boosting a stock ls7 with all the good parts. Most disasters come from tunes, and valves dropping.
If a stock "block" ls7 is tuned right and has all the goodies then you should be fine for many many happy boosted miles...
Oh, HKE builds nice ls7 SBs!!!!!

To help a stock aluminum block live a main girdle from DM Performance or billet main caps that are pinned is a good idea. I used a DM girdle in my last motor. You have to have it installed and torqued, then line hone the mains.

each way i juggle the numbers it still works out cheaper n better to buy a crate texas speed built engine with prc heads n forged internals for 13k and sell my stock engine for 6k. 7k upgrade. most builders want more than 7k that just to redo my heads and add a set of pistons to an otherwise stock ls7. crate engine im getting better parts and build for less money. custom quote below
Base Price: $10,624.99
Customized Price: $13,208.98

I wouldn't trust Texas speed to build my lawn mower. Too many horror stories floating around the interwebz. Your engine is not somewhere to shop like you're the government going with the cheapest bid.
