Brand new ls3 block deck flaw need help hi I recently bought a new ls3 block and the block has a casting flaw on deck. Should I be concerned? Also the steel liner looks like there is a gap between steel liner and aluminum casting. Please see pics.
Thanks
richard

its not uncommon for them to be like that around the liner mine was similar although yours is a bit worse than mine was my machine shop told me it would be fine I would ask your machine shop tho to be safe

My crate LS3 had a bit of a gap between the liners and the block as well. It seems the aluminum casting doesn't quite cover 100% of the liner surface as it flows into the mold. I suspect that structurally, it must not be significant, as they probably all have this to some degree--even below the deck where it is not exposed.
Mine did not have the surface imperfection yours has. I am not sure if that is something to be concerned about.

Ive fixed dings like that with high temp metal epoxy. They make it in aluminum for industrial Air Conditioning applications like repairing ex-changers or pumps. Then just use a small block to smoooth it flush.
But usually its damage not a void, one option might be to have someone ultrasound the block just to make sure there are no serious voids in the casting.
