Well here it is torn down... I hope the lifter bore can be saved, everything else looks fine. (ignoring the smashed skirt and dinged up reluctor) Thanks Joe!
Smashed Piston
Lifter bore
Cyl Wall looks good
Other side #7 looks good, you can see the gouge where the lifter came out, upper right
And here is my collection of LS parts... Likely going to rob that 5.3 of most of its dressing and use this block, I've already got a pair of good pistons and a crank in the basement from when I was considering making an iron 5.7
