For the money the LSX block is by far the strongest block on the market. It can withstand anything you throw at it and now they offer a tall deck! Im building an LSX 440 and wanting to get 700hp n/a.

From what I understand, the LSX blocks are typically used for power-adder/boosted applications.
Maybe I am wrong, so please feel free to correct me.
Another consideration is the additional wieght of an LSX IRON block. The LSX block is 100lbs heavier than the lS1. This is a significant amount of wieght to be adding to the nose of the car. People spend Thousands of dollars on lightweight wheels, drag-brakes, k-members, ext.. to take 100lbs of the nose of their car.
LS2/LS7 blocks have taken people deep into the 9s... and I am sure they have been deep into the 8s as well.
Bigger is not always better. Don't just blindly buy an LSX block w/o considering the other factors...

Why would you do that? The ls7 block is more than adequate for an NA build of that caliber.

460 ls2 sounds very nice. I would assume that would be an NA only build?
Sorry for the , but Blanco - What is the largest CI ls2/ls7 motor you would recommend for a large N2O shot? (say 200-300, with a good tune).
