I have those from st2 installs where we install new rods and pistons. I have plenty of them.
Also I suggest to diagnose what parts are broken, and may buy better upgraded parts beside stock ones. It is wery hard to kill all the parts in the engine at once.
Maybe your shortblock and head are ok, but would need boreing, rods and new pistons. I would suggest rather buy wiseco pistons and Crower rods, beside to get a hole new or used engine.
So make the diagnosis and do a calculation.
(internals also will let you go st2)
