Im going to have to go with the lsx. It has thicker cylinder walls to handle much higher cylinder pressures witch comes with running boost or nitrous. On the down side it does weigh a bit more, but the gain is well worth the extra weight.
iron is more durable than aluminum, the LSX block is what we use with our big boost/n2o builds

Its aluminum and its the same size as the G8 GTs L76 engine, It just has a slightly taller deck height to allow for more stroke like all tall deck blocks.
What woudld intrigue me is that it looks like you can swap lifters without pulling the heads!

How much power are you looking to make and whats your budget and what is the application. Those are the questions that need to be answered to make informed decisions.

I want to reach 1000RWHP+ and my budget is all right
I want first to know what block that can take this amount of power safely,isnt heavy and a good price,the top end and bottom end I already know
and what block cubes are best for this application

Its all about your budget and knowing what you have or want to spend on it.
You can go as inexpensive as an 6.0 iron block or as expensive as a billet aluminum block.. comes down to budget.. and one persons

all right budget
is another persons constraints.
In additon the cubes your going to run should have already factored into the block decision and since you already know the cubes and top end and bottom end not sure what your asking

I own a g8 GT that puts out 427rwhp and 397rwtq cammed and headers...
I don't think he knows what he's getting into. The rear end in our cars won't hold that much power they are already blowing them up in australia with less. Usually in the 700-800 range...There are no aftermarket companies making diffs for our cars.
To even come close you would be looking at a $1000+ driveshaft hendrix or someone else is making them can't remember... ours is weak and people are having failures at my power level already. Ours is the weak two piece with the rubber coupler.
a $2500 build on the trans to beef it up from rossler is what I was quoted thats good to over 1000hp.
You'll need new engine mounts ours will shred pfadt has some not sure on price.
You will need bmr trailing arms and all new bushings throughout the car or you will wheel hop bad.
You'll need a custom fuel system there are a couple of twin in tank setups being prototyped now, but nothing is ready yet.
Next problem is you will need CCW to custom make you some rims as there is nothing in the market that will fit a wide enough tire with our weird offsets in the rear.
You will have to put $20000-25000 minimum into our $30,000 car to even think about hitting 1000rwhp and not totally blowing your driveline to pieces...
If you have that kind of budget I applaud you... I'm simply looking at a 440 sleeved stroker setup or a maggie setup and be happy with my 550-600hp...
