Pics of said monster. Bare long block, yes. Retarded potential, yes.
I get the 823 heads are the newest LS3 casting number. But the block number I haven't been able to nail down as to original application. Is just like to know exactly what I'm working with.
Yes it's all aluminum. The LS9 blocks are reinforced for the boosted application. And have piston oil cooling nozzles. That's why I'm trying to decode that block number for sure. But that said by the looks of reading last night there's a metric **** ton of boosted standard LSx engines running around. I'm not worried either way. Just would like to know if it's the better block or not.
You wouldn't happen to know what it was removed from would you? I can pull up the internal info through GM service info. You wouldn't happen to have the supercharger with the ls9 would you?
