Durability of stock Pistons and rods..

So with the planned build of the 6.0 super truck, I am planning on pushing out big numbers in terms of HP. My question is how well would the stock pistons and rods with all the related parts hold up under severe work before they explode? Anyone have pistons or rods break due to HP?

A guy in a diesel power mag article has a work stock puller with a stock bottom end that dyno'd at like 750 hp and like 1200ft lbs. idk how often it's used or how it's used other than pulling but there's a start for ya lol.

What do you consider servere work lol?

Personally I don't think they would be having a very happy life in 600-700 rwhp under medium work.

Depending on your definition of "severe" id probably keep it around 500 rwhp if it was me but again that is largely dependent on your definition and what you plan on doing.

Mine is just north of 500 rwhp and I can say that putting this much power down is plenty to keep me happy.

But I work for a diesel shop... Therefore I will be pushing the hp rating up higher anyway

I will be listing a mod list later on this evening in a build thread.. Now mind you i wont be WOT 100% of the time but I do like to have fun and pull and drag. I want to be worry free if I am pushing 50 PSI of boost through race heads and not having to worry about my pistons going through those said heads.. 600-650 would be in the drive around town red light to red light application. With that being said, I am just curious on their strength only because I have on found a few sets of actual after market race rods but more pistons. Maybe you guys could point me in a direction of a supplier if you know any good ones.

FWIW mine has lasted through multiple 800+ dyno runs, a handful of 800+ 1/4 runs and still going strong. The only thing that has let go has been the head gaskets. Best numbers are 865hp 1450tq dyno and a 10.93@123. Stock bottom ends are very stout

I would say if your planning on abusing the truck and if the truck has several thousands of miles I would do a engine build just for the added insurance. Fwiw Mr stone pusher abuses his and his lower end is holding up fine
