is this normal wear for a piston skirt? pulled my motor down today and found this, talked to my local machine shop and they told me this was very common in stroker motors with this size skirt. what are my options? can I reuse them? should I look for a smaller skirt piston?

I think part of the problem with strokers is the piston is very short because of the stroke.
I was also told by a machinist that a bad tune up and detonation can cause where like that and collapse the skirts (I had collapsed the skirts on a couple pistons in my old motor)

It can be helped with the proper piston to bore clearance, proper skirt taper, and finish on the bottom on the cylinder edge. Those skirts looks pretty torn up. I just had my motor apart with a 4" stroke setup and they actually looks pretty decent.

I have had good luck with Diamond pistons, maybe try a set of those on the setup and see if you have better results. I'd check the chamfer, and check piston to wall after the machine work is done.
