good to know. So, given LS7's still blow up quite offten that just proves the LS2-7 castings are too poor to get serious with.
LS9's will no doubt be stouter and have a better than 10mm deck thickness shared by the earlier LS series alloy blocks. How stable they are however will have to wait until a few serious engine builders have pulled them down and put them to the test.
BTW - A haigh block powered LS looks set to crack a 6 second pass making it the first LS block powered car to do so, hopefully within 2 weeks.... they ran a 7.0 last time out. The Ford mod block has already achieved that feat but is much heavier. So watch the LS forums for the big scoop and yehaa's once the LS gets its first 6. Turbo'd of course.
