So you bought a MMR1000 shortblock, then decided you wanted to exceed 1000 hp, so you then disassembled the motor (when it was still in running/working order) to build it to withstand more power and that's when you noticed the pistons?

Just trying to understand your post, because it sounded a little confusing. I also think it's a little harsh to bash a company without pics or a proper description of why you are upset with them. Just my .02

Ppl I bought a Shortblock from mmr the stroker 1000 well I decided to up the power above that 1000 make so I took apat my short block and you won't believe what these pistons look like with only 1400 miles on them for some reason it won't let me upload pic but once I can I will upload pic

You should probably contact someone to help you type out some actual real sentences and words so we can properly understand what the **** you are saying. That would be a good start to this worthless thread. Maybe throw in a few pics to seal the deal? I dunno. Your call OP

Oh great, sounds like we have "highly detailed" cell phone pics incoming. This should surely prove the situation.

Download photobucket app, upload pics to photobucket, share on site from pc.

From what ive seen and read, piston and cylinder scoring can be cause by a few things including:

Improper cylinder honing (not using a torque plate.. Having out of round cylinders)
Not deburring rings properly
Not chamfering the bottoms of the cylinders
Dirty oil or debris in the oil due to dirty assembly

Most cases seem to point to improper machining/assembly. Are all of the pistons like this?
