Most definately a upgrade.
The LSX block is superior to all the other blocks made.
6 Bolts per cylinder for the heads will greatly aid in clamping force as the LS motors are know to push water .

I thought the LS3 also had a 6 bolt head design. Isn't the LS3 block stronger then the LS2? The LSX block is also much heaver though, so why would you want the iron block if you were looking for 800 hp or so? Again I don't know so that's why I ask.

Only gm block with 6 bolt is the LSX iron block . It is 100 lbs heavier.
Ls2 and LS3 block are most likely about the same for power capabilties.

No, the LS7 block is weaker than LS2/LS3 blocks. Although, in pro-touring car do you need more than 1200 hp? Also, the LS2,LS3, and LS7 blocks allow you run Katech Piston Oil squirters. Something that you might want to include on your next supercharged/turbo build.

.. the only reason its rated at 800 hp is because of the block ,crank rod combo.with the block crank and rod upgrade the motor makes over 1300hp...But the block is heavier but i think everyone could live with that.

The sleeves of the LS7 block take out so much material out of the block itself. GM even says the LS7 is not deigned to handle boost which is why they put a blown LS3 under the hood of the ZR1. They added some more doodads and changed a couple more parts and called it an LS9. It's a fancied up LS3 at it's core though. The ZR1 is only running 10 psi too and GM wouldn't let the LS7 be used because of long term durability.
