Pistons specs question for 340 build

Nat said
Mahle are really good pistons use them on my last 340 build DSS MAKE SOME GOOD PISTONS AS WELL using them on my stroker build , they custom made me a set if -13 cc dished pistons and they all weigh in at the exact same weight 635grams , they were made and delivered in 3 weeks . Either way thy are both quality pistons

Thanks for the tip and the weight. I'm just about to try and call up UEM to see if they have a weight for the KB 340 piston. I checked Mahle on Summit Racing but they are too expensive for me.
