so ya'll don't think it looks too bad???
I am unsure of the piston to wall clearance, I let the machine shop handle that. he said something about turbo charged engines having to have the rings cut differently than n/a engines I remember. and also said something about the clearance for forged pistons being different than cast. I guess I assumed he knew but I could've been wrong. Is there a way I can check the piston to well clearance accurately? through a micrometer maybe??? If I can, I'll check and tell ya'll on here what it is

I doubt it, these people were pretty redneck lol. I'll start by just measuring the bore size with the bore measuring tool and then if that seems off then I'll try and get info from the machine shop. Thanks for ya'lls opinions it really helps out. don't wanna put it all together again unless I know it'll last a while
thanks for ya'lls posts,

But you don't know the size of the pistons.. or if you do, can pistons be a bit different in size? Would this be significant enough in the gap size? When you measure a piston to bore clearance I think generally you use an outside micrometer around the piston, and then put the bore guage between the micrometer and zero it out. Then when you put the bore guage in the bore, the dial reads the difference or gap.
Generally what are the signs of problems when looking at a cylinder wall?

Summit Racing will have bore guage for you.

Our engine builder says that the walls do not look that far off from a normal stroker.
Strokers put more side load on a pistons and can cause what you are going through.
I would make sure the tune is in check as detonation and too much fuel can cause this to happen much quicker and more severe.

The Evo X's came from the factory touching in the 9's! So I'd hazard a guess 10.5 on boost would not be a problem. Although I believe there was a recall or bulletin to correct the over rich X's... but I'm not too clued up on them really so could be wrong.
