Very well. That may one of the best blocks you could choose. The iron blocks are really strong and will keep internal clearances closer to set specs than a an aluminum block. that is why, if your going big with the spray, like 300hp area the LQ9, buck for buck, can not be beat. what happens when we get giant cylinder pressures on the spray, stuff starts moving around on the aluminum blocks, where as the iron blocks are much more stable and will likely out live the aluminum when rebuilds are considered. I think the iron blocks do a better job of allowing the heads to stay down. that's the block I choose for my sprayed motor build and had it spec'd to handle 1000hp should I ever feel the need to have that kind of power. My motor, with bone stock LS6 heads and stock LS6 intake along with a small cam made 430rwhp, and i can hit it easily and safely with a 300rwhp shot and expect it to live a nice long time. If you have the money, that motor can put out 500rwhp n/a for a truly bad azz street/strip motor and still hang on to things like A/C. Good luck and keep us updated on your build, what ever you decide to build, lol.

Your weakest link will likely be the rod bolts and stock pistons, because it's the stock rotating assembly I'd worry about. If I read your post correctly anyway.
