Aluminum Vs. Iron Block "The real deal"
The LS1 series engine was designed from its inception as an Aluminum block. By starting out with an aluminum block, the designers added many features to ensure long life and strength. Some of these included the ribs on the outside of the block, and the deep skirt and 6 bolt mains. The Aluminum block is very strong!
NOW having said that, when GM started producing the Iron LS1, it was less expensive for GM to use the same casts for the Iron motor and the Aluminum. What does this mean? It means that the same design features that were used to stengthen the aluminum motor are included in the Iron block. Quite simply the Iron block is the STRONGEST small block GM motor Ever produced. I had a great chat with the head of GMPP at SEMA last year. That was just a few things we talked about.
He also hinted at a factory large bore Iron block in the works...

He also said they are about to release a single LARGE intercooler for people that are going big.

Or why not get the higher compression motor put 4-5# of boost and cam it properly and get some big numbers.
Or put stronger rings\pistons in your ls1 with a proper cam. The rings are the only weak area. That is a 550rwhp easily.
I am sure you have been thinking about all these options.
