Aren't the LSA and LS9 blocks the same save for larger bolt holes in the LS9? I could've swore that was the biggest change. I know they both have the piston squirters, but I thought all newer 6.2L blocks from '08 and up are cast the same with the same heat treatment, with the one exception being that one element from the LS9...
I think I'd like to see if one could get a couple more pounds of safe boost out of that LSA. I'm sure those hyper' pistons are better suited to boost than the stock LS3s, but I'm sure one couldn't go to radical.
