How does that compare to a standard aluminum block?
+100 to 120 pounds

They have not been tried yet for max CI. They are just like any LSX block in the way they bolt up to an LS vehicle....stock mounts. The NEW block comes with a slightly smaller starting bore, that can be finished out with a 3.622 crank for a 346....we have built them to a 468 before off of a 4.185 bore. Hint: it takes alot of stroke to pull that one off. These newer castings will be insteresting, but if there is just a little more room like gm says, then 470+ CI from this standard deck would not be too much of an issue. Trying to go much more than that is probably pushing it IMO
these are just the blocks themselves, so headers will have to match the heads/cam/CI combo. 1 7/8 is recommended on anything like this really to start.
They told us they were shipping, but we will hesitate to post until they show up.
