Does anyone know where I can buy a stock replacement piston for my 250 6 cyl? I tried NAPA and Advanced Auto Parts but no luck.

I had a local machine shop order mine but you can get them off Summit Racing.

Thanks Mike! Is it the Sealed Power 403P part #?

If you need just one, make sure the new one is weighted the same. I couldn't find one that was weighted even close so I had to replace all the pistons.

I was planning on only replacing the damaged one but didn't realize the weight issue. I can replace all of them just need to know what the stock measurements is or a part # so I can order them.

You will definitely want to contact a machine shop. Get the piston weighed and see if they can get you something that weighs the same. Pistons can have huge differences in weight. It will be measured in grams and without measuring what you have there is no real way to know.
