Pistons specs question for 340 build

Just had a look at the PDF that Nat posted the link to. That has now given me a very good idea of weights. The Mahl PowerPak piston range goes from 470g to 512g. The heaviest one being what my engine is: standard stroke 340 + 0.030. So that SRP forged I mentioned previously at 462g is quite light. If there is only a few grams difference between the KB Hypers and the DSS FX1 (ie if the KB's are bit lighter) I might still buy the DSS. They also offer a ring package as well.
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
