Some of you will have seen this in YB. I thought I would post it here also. Looking for input from engine builders, or from people that have sprayed big shots. I know there are several people running this block in real street spraying 250 worth. I'm wondering if the block will take 400, without going through extreme machine work like an ERL block gets.
Thanks
Roger

The LS3 block should be good for 600-700 fairly safely. Some push more with no negative results...some blow up with less.

600 total is about the "safe" ballpark.
