I ran a texas speed 229 LS3 grind in my LY6 6.0 it ran 11.0's on motor and 10.0's on 150 shot in a 3400 lb. mid size truck. Properly matched up combo.

There is quite a few threads on this around LS1tech. It depends on if you want to fly cut the pistons or not. If not, a few companies offer max effort ls3 cams for those who wont be fly cutting. I think you are limited to an intake duration in the low 230s @ .050". Also, there is a few threads where guys broke pistons above the ring land trying to spray stock pistons that were fly cut.

Cam, springs and pushrods no other internal mods. No flycutting.

It appears Texas Speed has done a lot of work to figure out how much cam will fit in an LS3 without fly cutting. You might do well to give them a call to pick their brains. Here is their max effort no flycut LS3 cam:
