WTB LS1 shortblock
You can see what appears to be scoring by shining a flashlight down in the port and what you see is what I described... the very bottom 1/16" of the port, and only on one side, isn't as shiny as the rest of the port. So I'm assuming there is a little scoring from the broken lifter but I can't feel anything out of the ordinary with my finger. It's nice and smooth, no burrs. Fortunately the engine was at idle when the lifter came apart and I shut it off right away.
A lifter slides up and down in the port very nicely and there is no binding, but I don't know for sure the extent of the damage beyond what is visible, but it appears to be minor. Again, it's just the bottom 1/16" of the port and the scoring is only half way around the port. I'll try and get a picture if you're interested.
Other than that, it ran very well until the lifter came apart, and as far as I know there are no other issues with the block, crank, or pistons. $1200 plus shipping.
